The Trinity and the Great Commission
Verse by Verse study of Matthew 28:16–20
Introduction
Matthew’s Gospel ends where the mission of the Church begins. The risen Jesus meets His disciples on a mountain in Galilee and entrusts them with His final command. These verses are often called the Great Commission, but they are much more than a command to evangelize. They reveal the authority of Christ, the mission of God, the work of the Trinity, and the continuing presence of Jesus with His people. Everything Matthew has written about Jesus—His birth, teaching, miracles, death, and resurrection—now leads to this moment.
Mission did not begin with the Church. Mission began in the heart of God. Throughout Scripture we meet a missionary God. The Father seeks and sends. The Son comes and saves. The Holy Spirit empowers and guides. The Church is invited to participate in this divine mission. As Lesslie Newbigin wrote, “It is not so much that God has a mission for His Church in the world, but that God has a Church for His mission in the world.”
This passage also reminds us that Christian mission begins not with human strength but with Christ’s authority. Jesus declares, “All authority in heaven and on earth has been given to me.” The disciples are not sent because they are powerful, confident, or fully prepared. They are sent because the risen Christ reigns. His authority is the foundation of their mission and the source of their courage.
At the heart of the Great Commission is the call to make disciples of all nations, baptizing them in the name of the Father, Son, and Holy Spirit, and teaching them to obey everything Jesus commanded. This is deeply Trinitarian. The Father sends, the Son commissions, and the Spirit empowers. The goal is not merely to make converts, but to form faithful followers of Jesus whose lives are shaped by His grace, truth, and love.
Finally, the passage ends with one of the most comforting promises in Scripture: “Surely I am with you always, to the very end of the age.” The One who sends His people also goes with them. Matthew begins with the promise of Immanuel, “God with us,” and ends with the assurance that Christ remains with His Church. As we study these verses, we are invited to worship the risen Lord, submit to His authority, join His mission, and rest in His abiding presence.
Opening Prayer
Lord,
Thank You for gathering us to study Your Word. Open our hearts to understand Scripture and see Christ more clearly. As we reflect on the Great Commission, remind us that the Father sends, the Son saves, and the Spirit empowers. Strengthen our faith, deepen our fellowship, and help us share Christ’s love wherever You place us. In the name of the Father, Son, and Holy Spirit. Amen.
Matthew 28:16–17 - Worship and Doubt
“Then the eleven disciples went to Galilee, to the mountain where Jesus had told them to go. When they saw him, they worshiped him; but some doubted.”
Matthew 28:16-17
The eleven disciples go to Galilee, to the mountain where Jesus had told them to meet Him. When they see the risen Christ, they worship Him, yet Matthew honestly adds, “but some doubted.” This is a striking detail. Worship and uncertainty stand side by side. The disciples are not presented as flawless heroes, but as real people still learning to trust. The Great Commission is entrusted not to perfect believers, but to imperfect disciples who have encountered the risen Lord.
Matthew’s honesty is deeply encouraging. The Greek word used for doubt, distazō, suggests hesitation or wavering rather than settled unbelief. Some of the disciples were caught between wonder and uncertainty. Yet Jesus does not reject them, rebuke them, or remove the mission from them. Instead, He comes near and commissions them. This reminds us that doubt does not disqualify us from discipleship. As Matthew 12:20 says, “A bruised reed he will not break, and a smoldering wick he will not snuff out.”
Throughout Scripture, God often meets His people in seasons of uncertainty. Abraham obeyed without knowing where he was going. Moses felt inadequate for the task. Elijah encountered God when he was discouraged and exhausted. Thomas struggled to believe until he met the risen Christ. In our own lives too, God often meets us through Scripture, prayer, the encouragement of others, and the quiet assurance that He has not abandoned us. David could say, “Even though I walk through the darkest valley, I will fear no evil, for you are with me” (Psalm 23:4).
Doubt can be destructive if it leads us away from God, but it can also become a pathway to deeper faith when it drives us toward Him. The Psalms are filled with honest cries such as, “Why, Lord, do you stand far off?” and “How long, Lord?” God is not threatened by sincere questions. Honest doubt can lead us to search the Scriptures more deeply, pray more earnestly, and depend more fully on Christ. Thomas’s doubt eventually led to one of the greatest confessions in the New Testament: “My Lord and my God!” (John 20:28).
A faith that has wrestled with questions is often stronger than a faith that has never been tested. Like gold refined by fire, faith can be strengthened through seasons of uncertainty. The prayer of the desperate father in Mark 9:24 remains one of the most honest and hopeful prayers any disciple can pray: “Lord, I believe; help my unbelief!” Jesus receives such prayers with compassion. Mission begins not with perfect certainty, but with worship, trust, and a living encounter with the risen Christ.
Matthew 28:18 — The Authority of Christ
And Jesus came and spoke to them, saying, “All authority has been given to Me in heaven and on earth.”
Matthew 28:18
Before sending His disciples into the world, Jesus first reminded them who He is: “All authority in heaven and on earth has been given to me.” The Greek word exousia speaks of rightful power, sovereignty, and the freedom to rule. The prophets spoke with delegated authority, saying, “Thus says the Lord,” but Jesus spoke with His own authority: “But I say to you.” Throughout His ministry He forgave sins, calmed storms, cast out demons, healed the sick, and raised the dead. Now, risen from the grave, He declares that all authority belongs to Him. Daniel had foreseen this moment when the Son of Man would receive an everlasting kingdom and dominion (Daniel 7:13–14). The Great Commission therefore begins not with human effort but with the lordship of Christ. We go because Jesus reigns.
The authority of Christ calls each of us to consider what areas of life remain outside His rule. We may gladly trust Him with our salvation while hesitating to surrender our future, ambitions, finances, relationships, health concerns, or family matters. Peter struggled with this when he resisted Jesus’ prediction of suffering and death. Like Peter, we often want Christ to be our Savior while holding on to control. Yet true discipleship means recognizing Jesus as Lord over every part of life. The question is not whether Christ possesses authority, but whether we are willing to live under it.
At the same time, Christ’s authority is unlike the authority exercised by the world. Human power often depends on position, status, force, or self-interest. Jesus exercises authority through humility, truth, service, and sacrificial love. He washed His disciples’ feet, welcomed the overlooked, touched the unclean, forgave sinners, and gave His life for the salvation of the world. As He said, “The Son of Man did not come to be served, but to serve” (Mark 10:45). His authority does not oppress but restores; it does not enslave but liberates; it does not exploit but redeems. The One who possesses all authority is also “gentle and humble in heart” (Matthew 11:29).
Because Christ reigns, His authority is also a source of profound comfort. Nations rise and fall, economies fluctuate, wars erupt, and life often feels uncertain, yet above hevery earthly power stands the risen Lord. Nothing is beyond His knowledge, His care, or His control. Even when we cannot understand what God is doing, we can trust His character and His promises. The One who rules the universe is also the One who loved us enough to die for us and who assures us, “I am with you always, to the very end of the age” (Matthew 28:20). Therefore, we face the future with confidence, not because we know what tomorrow holds, but because we know who holds tomorrow. Christ’s throne is occupied, His kingdom is advancing, and His purposes will ultimately prevail.
Matthew 28:19–20 Making Disciples
“Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, and teaching them to obey everything I have commanded you.
Matthew 28:19-20
‘After declaring that all authority in heaven and on earth belongs to Him, Jesus gives His followers their mission: “Go and make disciples of all nations.” He does not simply tell them to make converts, gather crowds, or secure quick decisions. He commands them to make disciples. A disciple is a learner, follower, and apprentice of Jesus Christ—someone who believes in Him, walks with Him, obeys Him, and seeks to become like Him.
There is an important difference between conversion and discipleship. Conversion is the beginning of the Christian life; discipleship is the lifelong journey that follows. A convert receives Christ by faith, but a disciple continues to grow in Christ’s word, Christ’s ways, and Christ’s character. Jesus said, “If you continue in my word, you are truly my disciples” (John 8:31). The aim of Christian mission is not merely to help people make a decision for Christ, but to help them build a life with Christ.
Discipleship is rarely a solitary journey. Most of us can look back and remember people whom God used to shape our faith—parents, grandparents, pastors, teachers, mentors, friends, or fellow believers. Barnabas encouraged Paul, Paul mentored Timothy, and Priscilla and Aquila helped Apollos understand the way of God more fully. Much of discipleship is learned not only through words, but through example. We learn by watching how mature believers pray, serve, forgive, endure suffering, worship, and trust God.
The Great Commission also moves us from receiving to giving. Every disciple is called, in some way, to become a disciple-maker. Not everyone is called to preach or lead publicly, but every believer can encourage someone else to follow Jesus more closely. Discipleship often happens through ordinary faithfulness—praying together, reading Scripture, sharing burdens, offering encouragement, and modeling Christian character. The question is not whether we have all the answers, but whether we are helping someone take the next step toward Christ.
Jesus’ command also reveals the truth of the Trinity. He tells His disciples to baptize “in the name” — singular — “of the Father and of the Son and of the Holy Spirit.” He does not say “in the names,” as though there were three separate gods. The word Trinity may not appear in Scripture, but it faithfully describes what Scripture reveals: one true God, eternally known as Father, Son, and Holy Spirit. Christian mission flows from this triune God: the Father sends, the Son saves, and the Spirit empowers. Therefore, we go not in our own strength, but in the name and presence of the living God.
Matthew 28:20 The Presence of Christ
“Surely I am with you always.”
Matthew 28:20
The Great Commission concludes with one of the most comforting promises in all of Scripture: “Surely I am with you always, to the very end of the age.” Before Jesus ascended to heaven, He assured His disciples that they would never be left alone. The One who sends them into the world also goes with them. This promise forms a beautiful frame around Matthew’s Gospel. It begins with the announcement that Jesus is Immanuel, “God with us” (Matthew 1:23), and ends with Jesus promising, “I am with you always.” From beginning to end, the Christian life is lived in the presence of Christ. His followers are never abandoned, forgotten, or left to carry out His mission in their own strength.
The word “always” deserves special attention. In the original Greek, Jesus literally says, “I am with you all the days.” He does not merely promise to be with His disciples in a general way or only during special spiritual moments. He promises to be with them every day, in every season, circumstance, and stage of life. There are no exceptions, no interruptions, and no expiration date attached to His promise. Christ is with us on ordinary days as well as extraordinary days, on days of joy and sorrow, success and failure, confidence and doubt. As Hebrews 13:5 reminds us, “Never will I leave you; never will I forsake you.”
This promise speaks directly to the challenges and uncertainties of everyday life. Most of us can identify situations where we long for Christ’s presence—family concerns, health struggles, difficult relationships, seasons of grief, important decisions, or fears about the future. Sometimes our greatest need is not an immediate solution but the assurance that we do not face these burdens alone. Jesus does not merely promise assistance; He promises Himself. The psalmist reminds us, “The Lord is close to the brokenhearted” (Psalm 34:18). Often the deepest comfort of faith is not that God changes our circumstances immediately, but that He walks with us through them.
Many believers discover God’s presence most clearly when looking back over difficult seasons. During times of suffering, confusion, or uncertainty, God may seem distant. Yet later we recognize how He sustained us through a timely Scripture, the prayers of friends, unexpected peace, renewed strength, wise counsel, or comfort in grief. David testified, “Even though I walk through the darkest valley, I will fear no evil, for you are with me” (Psalm 23:4). God does not always remove the valley; instead, He accompanies us through it. Christ’s presence is continuous, not occasional. It is not dependent on our feelings, circumstances, or awareness of Him. His presence is a fact before it is a feeling.
The promise of Christ’s presence also empowers us for service. The Great Commission begins with Christ’s authority and ends with Christ’s presence. The same Lord who declares, “All authority in heaven and on earth has been given to me,” also says, “I am with you always.” Our confidence therefore rests not in our abilities, experience, or strength, but in His faithfulness. Just as God assured Moses, “I will be with you,” and encouraged Joshua, “I will never leave you nor forsake you,” so Christ accompanies His people through the Holy Spirit today. His presence gives us courage to take risks in faith, perseverance to continue serving, and confidence to share the gospel. Because Christ is with us “all the days,” we can move forward in faith, trusting that His purposes will prevail until the very end of the age.
Conclusion
Matthew’s Gospel concludes with a mountain, a commission, and a promise. The disciples stand before the risen Christ, worshiping Him, though some still struggle with doubt. Yet Jesus entrusts His mission to them. This reminds us that God does not wait for perfect people before calling them into His service. He calls ordinary men and women who are willing to trust Him, follow Him, and participate in His work.
The Great Commission reveals the heart of the Triune God. The Father planned redemption, the Son accomplished redemption, and the Holy Spirit applies redemption. The Church is then called to proclaim this redemption to the world. Mission is therefore not merely a church activity; it is participation in the ongoing work of the Father, Son, and Holy Spirit. The Father sends, the Son saves, the Spirit empowers, and the Church bears witness.
Jesus’ command is not simply to gain converts but to make disciples—people who learn from Him, obey Him, and become increasingly like Him. The Great Commission does not necessarily mean traveling overseas. It means living as Christ’s witness wherever God has placed us. Some cross oceans. Some cross streets. Some preach to crowds. Others faithfully serve family members, neighbors, friends, and colleagues. As David Livingstone wrote, “I am a missionary, heart and soul. God had an only Son, and He was a missionary and a physician. A poor, poor imitation I am or wish to be.” That is Christ’s call to every believer—not necessarily to a place, but to a posture of heart.
The commission is grounded in Christ’s authority and sustained by Christ’s presence. Because He reigns over all things, we can go with confidence. Because He promises to be with us always, we never serve alone. The Christian life is not sustained by our ability to hold on to Christ, but by Christ’s faithfulness in holding on to us. When the road is difficult, His presence comforts us. When the task seems overwhelming, His presence strengthens us. When the future is uncertain, His presence reassures us.
Matthew’s Gospel begins with Immanuel—“God with us” (Matthew 1:23)—and ends with “I am with you always” (Matthew 28:20). The entire Christian journey is lived between those two promises. Therefore, whatever challenges we face today, we can move forward with confidence, knowing that the risen Lord is not merely watching from heaven but walking with us every step of the way.
The Great Commission begins with worship and ends with promise. It reveals the authority of Christ, the mission of the Triune God, the calling of the Church, and the abiding presence of Jesus. The question is not merely, “Where is God sending me?” The deeper question is, “Am I willing to participate in the mission of the Father, Son, and Holy Spirit?” Until the day when people from every tribe, language, people, and nation gather before His throne, Christ’s command remains our mission, and Christ’s promise remains our hope: “Surely I am with you always, to the very end of the age.”
Closing Prayer
Lord,
You are our Creator, Redeemer, and Sustainer. We praise and adore You, whose glory shines throughout heaven and earth and whose mercy endures from generation to generation. You are our hope in times of uncertainty, our honor in a world that often seeks its own glory, and our refuge when we are weak and afraid. Deliver us from sin, self-reliance, and unbelief. Free us from everything that hinders our obedience to Christ and our witness to the gospel. Teach us to surrender every area of our lives to Your loving authority and to follow wherever You lead. May our lives reflect the love of the Father, the grace of the Son, and the fellowship of the Holy Spirit. Keep us faithful in worship, joyful in service, steadfast in hope and lead us in Your ways, now and forever.
Amen.
