From Doubt to Commission: Stepping Out in Faith

Matthew sets Trinity Sunday on an unnamed mountain where worship and doubt sit side by side. The text places the risen Jesus before the Eleven, and Matthew refuses to tidy the room. “They worshiped him, but some doubted.” That line stays on the page. The mountain becomes the stage where shaky knees bend, not after certainty arrives, but right in the middle of uncertainty. The surprise is that Jesus does not pause to fix the doubt. He does not separate the strong from the weak. He steps straight into the uncertainty and speaks.

Jesus grounds everything in his sovereignty. “All authority in heaven and on earth has been given to me.” That claim, not the disciples’ confidence, carries the weight of the mission. The commission then stretches out beyond Galilee and Judea to “all nations,” pulling the horizon open so that every person and every corner of the world stands in view. The task is clear and concrete. Go, make disciples, baptise “in the name of the Father and of the Son and of the Holy Spirit,” and teach the obedience that grows from his commands. The Trinitarian name is not an abstract puzzle to solve, but the living name into which people are drawn and sealed.

Peter’s past wobble on the waves echoes here. Matthew uses the same word for doubt, inviting the memory of Jesus catching him before he sank. That echo signals grace. The commission lands on worshippers and wobblers alike. Faith here is not the absence of questions. Faith is stepping out when the depth of the water is still unknown. The authority of Jesus steadies the step.

The promise then closes the passage and holds the church together. Emmanuel bookends Matthew. God with us at the beginning, and at the end, “I am with you always, to the end of the age.” That word speaks into rooms where budgets do not balance and courage feels thin. It answers the instinct to walk away by naming a presence that has already gone ahead and also stands here. The question is not whether a church can afford to be a church. The question is whether trembling knees will bend and worship in the uncertainty, then rise and go. It is not about them. It is about going. From a hillside in Galilee to Bells Hill and Bothell, the commission starts where doubt often sits, and from that soil a sturdy faith slowly grows, not for a few, but for all people.

Key Takeaways

• 1. Doubt kneels beside true worship Doubt does not disqualify discipleship; Matthew lets worship and uncertainty inhabit the same sentence. The mixed heart is the very place Jesus meets people, not a problem to be solved before obedience. Faith often begins where vision blurs and knees wobble, because trust is not sight. The surprise is that sacred awe and honest questions can share one prayer. [37:10]
• 2. Jesus commissions wobblers and worshippers Jesus does not wait for the unsure to become steady. He gives the same charge to the confident and the conflicted, because his word makes a people before their courage catches up. Calling precedes clarity, and mission becomes the forge where conviction is tempered. Grace gathers the whole room, not just the polished few. [38:55]
• 3. Authority fuels mission, not bravado “All authority” belongs to Jesus, so the church’s going does not lean on bravado, charisma, or perfect plans. The mandate rests on his reign, which frees ordinary people to take ordinary steps with extraordinary purpose. Obedience grows from trust in a living King, not from moods or metrics. The scope to “all nations” is credible because his rule already spans that map. [39:20]
• 4. Emmanuel steadies courage in scarcity “I am with you always” lands where resources feel thin and risks feel large. Presence becomes provision, not by erasing figures on a page, but by carrying a people through them. The path ahead may still feel deep and dark, yet companionship turns danger into pilgrimage. Courage rises when the church remembers who walks the road. [44:12]

4. In Matthew 14:31, what does Jesus identify as the root of Peter’s doubt, and how does He respond?

1. Why might Jesus have chosen to commission the disciples while some were still doubting, rather than waiting for their uncertainty to resolve? [39:59]
2. How does Jesus’ claim of “all authority” (Matthew 28:18) change the way we understand the church’s mission in the face of practical challenges like financial shortfalls or fear? [43:14]
3. The sermon suggests that “faith is stepping out when the depth of the water is still unknown.” How does Peter’s experience in Matthew 14:28-31 illustrate this idea?
4. What does it mean for the Trinitarian name (“Father, Son, Holy Spirit”) to be a “living name” rather than an abstract doctrine in baptism and discipleship?

1. When have you felt both worship and doubt coexisting in your faith journey? What practical step could you take to bring both to Jesus instead of waiting for certainty? [37:10]
