Key verse: “For you are setting your mind not on divine things but on human things.” – Matthew 16:23
Oh, Peter! In chapter 16 of Matthew’s Gospel, we encounter the disciple Peter in the best of times followed almost immediately by the worst of times. Through Peter’s wild swing from wise leader to misguided stumbling block, we learn alongside him about a crucial but often overlooked form of faithfulness: the stewardship of the mind.
It’s worth stepping back to see just how well Peter was crushing it right before this week’s reading. In Matthew 16:13, when Jesus asks the disciples who they believe he is, Peter doesn’t hesitate: “You are the Messiah, the Son of the living God.” Jesus commends him and declares Peter the rock upon which the church will be built. Wow! What a time to be Peter!
Then comes this week’s text. This is a significant pivot point in Matthew’s Gospel. From here on out, Jesus begins preparing his friends for the reality of his coming suffering, death, and resurrection. But Peter isn’t having it. He pulls Jesus aside and attempts to rebuke him.
The intensity of the moment is palpable, and Jesus meets Peter’s anxiety with sharp fervor: “Get behind me, Satan! You are a stumbling block to me; for you are setting your mind not on God things but on human things.”
Jesus then expands the teaching moment to include all the disciples as his hearers. Discipleship, Jesus explains, means denying ourselves, taking up our crosses, and losing our lives for his sake in order to truly find them.
Good stewards take excellent care of what has been entrusted to them. We often think of stewardship in terms of time, talent, and financial resources. This text invites us to explore what it means to steward our minds – both individually and collectively. What does it actually look like and feel like to set our minds on “God things” rather than “human things”?
And what about when we get it wrong? What do we do when our minds get trapped in loops of doom-scrolling or toxic nostalgia or self-preservation?
The struggle is real, and God walks with us. We even see Jesus himself navigating a shift in perspective in Matthew’s Gospel. While he might have preferred to remain in the familiar rhythms of teaching and healing and being with his disciples, Jesus recognizes the call toward Jerusalem. In setting his mind on God’s larger vision, Jesus releases control of his own path, and he invites the disciples into that same transformative freedom.
This week, congregations get to wonder together: How is God inviting us to steward our minds in more intentional ways? What comfortable narratives or anxious fixations are we being asked to release into the hands of our Creator? As we step into the activity and fullness of fall, where is God inviting us to direct the attention and energy of our minds?
Peter’s journey, moving from clarity one moment to confusion the next, is deeply relatable. Sometimes we get it; sometimes we don’t. But the good news of the Gospel is that Jesus doesn’t abandon Peter – nor does he abandon us. He meets us right where our minds are, offers guidance and grace, and invites us to keep walking forward together.
In Worship
Prayer of the Day: Pray for God to renew our minds, untangle our worries, and clear away the mental noise that keeps us from seeing divine possibility.
Prayers of Intercession:
- Include petitions specifically for those experiencing mental health challenges.
- For those trapped in loops of anxiety, doom-scrolling, or despair.
- For leaders carrying the heavy weight of complex decisions.
- For communities stuck in “toxic nostalgia,” that God would grant them a fresh vision for the future.
Offering & Hand-Releasing Movement: Before the offering plates pass, invite the congregation into a brief body prayer: “Hold your hands in tight fists in front of you. Feel the tension of holding on – to control, to plans, to fear. Now, slowly open your palms toward heaven. In this posture of release, we surrender our thoughts, our resources, and our lives back to the God who holds them.”
With Youth
The Peter & Jesus Dynamic: Peter loved Jesus, but he tried to dictate Jesus’ path. Ask teens: Have you ever had a friend who wanted what was best for you, but didn’t actually understand where you needed to go? How do you set boundaries when a friend’s advice pulls you off track?
Denying Yourself vs. Self-Care: Nurture a small group environment where youth can wrestle with Jesus’ call to “deny yourself.” Clarify that denying yourself isn’t about accepting abuse or hating yourself; it’s more choosing not to put your own preferences at the center of the universe. Wonder together – how might we deny ourselves while also holding deep respect and regard for ourselves as beloved children of God created in God’s image?
Media Connection: Discuss characters in pop culture who had to choose a hard path over a comfortable one.
With Children
Children’s sermon:
Props needed: Toilet paper tubes and/or paper towel tubes; and a colorful, large picture or poster.
Start by having the kids look through their tubes at a tiny detail of the large picture. Ask: “What do you notice?” Then ask: “As you look through the tube, can anyone tell me what this whole picture is?” (They will guess, but it’s hard to tell if they’re only looking at one little piece!) Then, tell them to put the tube down and look at the whole poster; they can then see the whole scene.
In today’s story, Peter had what is called tunnel vision! He was so focused on what he wanted right in front of him – a safe, easy path for Jesus – that he couldn’t see the huge, beautiful picture of God’s love that Jesus was painting for the whole world. Jesus had to tell Peter to step back so he could see the big picture.
When we get angry, scared, or stuck on having our own way, our minds get tunnel vision. We can only see a little bit of the picture. But God calls us to be stewards of perspective (or stewards of our minds) – asking God to help us zoom out, see others with love, and trust in God’s bigger picture.
