13th Sunday after Pentecost

Devotional

Day 1: Sacred Trust in Worn-Out Floors

The preschool’s sixty-year legacy isn’t about pristine classrooms but crayon-smudged walls and floors worn smooth by tiny feet. Every diaper changed, every snack served, every chapel lesson whispers that God claims even the smallest spaces. Teachers and administrators don’t just manage routines—they baptize ordinary moments with eternal purpose. When crayons break and tears fall, the sacred work isn’t interrupted—it’s revealed. This is how God builds His kingdom: through peanut butter sandwiches and mismatched socks. [35:25]

“Let the little children come to me, and do not hinder them, for to such belongs the kingdom of heaven.” (Matthew 19:14, ESV)

Reflection: Where do you sense God’s presence most clearly in the “worn-out floors” of your daily work? How might your hands bless what others dismiss as mundane?

Day 2: “Who Do You Say I Am?” in the Carpool Line

Jesus’ question to Peter lingers in school drop-offs and staff meetings. Confessing “You are the Messiah” isn’t reserved for altars but erupts in math lessons and playground conflicts. The rock of faith isn’t a doctrinal statement—it’s the steady rhythm of showing up, declaring through actions that Christ inhabits ordinary time. When toddlers ask “Why?” or teens roll their eyes, the answer remains the same: He is here. [38:43]

Simon Peter replied, “You are the Christ, the Son of the living God.” And Jesus answered him, “Blessed are you, Simon Bar-Jonah! For flesh and blood has not revealed this to you, but my Father who is in heaven.” (Matthew 16:16–17, ESV)

Reflection: When has your daily routine unexpectedly become a confession of faith? How does “You are the Christ” reshape your view of today’s to-do list?

Day 3: Custodians and Calculus Teachers as Kingdom Witnesses

God needs no stained glass—He hallows mop buckets and whiteboard markers. The custodian’s pre-dawn sweeping testifies as powerfully as the pastor’s sermon. Every vocation becomes a pulpit when done “as unto the Lord.” Algebra equations teach order, art classes reflect creativity, and lunchroom laughter echoes joy—all declaring the Creator’s fingerprints. Your work isn’t incidental to ministry—it is ministry. [44:10]

“Having gifts that differ according to the grace given to us, let us use them: if prophecy, in proportion to our faith; if service, in our serving; the one who teaches, in his teaching; the one who exhorts, in his exhortation; the one who contributes, in generosity; the one who leads, with zeal; the one who does acts of mercy, with cheerfulness.” (Romans 12:6–8, ESV)

Reflection: What overlooked corner of your work most clearly reflects God’s character? How might you lean into that today?

Day 4: Moving Trucks and New Beginnings as Holy Ground

College move-in days and first-day jitters are altars. When unfamiliar dorm rooms feel lonely or lesson plans unravel, “I AM” dwells there too. Transition isn’t a disruption to faith—it’s the terrain where God meets us. Packing lists become prayer lists; nervous introductions bloom into divine appointments. Wherever you’re planted—classroom, office, or freshman hallway—you carry the Rock that anchors every storm. [42:19]

“God said to Moses, ‘I AM WHO I AM.’ And he said, ‘Say this to the people of Israel: “I AM has sent me to you.”’” (Exodus 3:14, ESV)

Reflection: What anxiety about change could become an opportunity to declare “I AM is here”? How does God’s eternal “now” steady your heart in transition?

Day 5: Engineers and Educators Bearing the Messiah’s Name

Your title—teacher, parent, student, engineer—isn’t a label but a commission. Changing diapers and solving equations both answer Jesus’ question: “Who do you say I am?” The world hears “Messiah” through your patience with tantrums, integrity in deadlines, and joy in discovery. You need no clerical collar—your faithfulness in the daily grind preaches louder than any sermon. [43:43]

“As each has received a gift, use it to serve one another, as good stewards of God’s varied grace… in order that in everything God may be glorified through Jesus Christ.” (1 Peter 4:10–11, ESV)

Reflection: How does your specific skill set uniquely declare Christ’s love to your corner of the world? What ordinary task today could become an act of worship?

Sermon Summary

The back-to-school blessing begins with gratitude for a church that has been entrusted with children for more than sixty years. Christ’s day school preschool stands as a real ministry of the church, not an extra thing off to the side. The trust of parents is sacred because they are bringing their babies, literally their babies, into the care of this place. The vocation of teachers is named as ministry, not in a scary way, but in the good and holy sense that their work gives witness to God.

The church building itself is meant to be used, worn out, filled with kids playing, learning, growing, and coming into the sanctuary for chapel. The care of little ones, even in ordinary things like changing diapers, becomes a witness to who God is and who God’s people are called to be. The words “I am” carry deep meaning because God gave that name to Moses from the bush. Jesus’ question, “Who do people say that the Son of Man is?” is not a trick or a test, but a calling forth of confession.

The answer of the crowd names John the Baptist, Elijah, Jeremiah, or one of the prophets. Jesus presses closer and asks, “Who do you say that I am?” Peter’s answer, “You are the Messiah, the Son of the living God,” becomes the rock. The rock is not finally a personality or a position, but the confession itself. That confession says that Jesus has come in flesh and blood, lived, died, and risen so that life and hope may be given.

The call of the school year is therefore witness. Romans names different gifts: prophecy, ministry, teaching, encouragement, generosity, leadership, compassion. Those gifts belong not only to people wearing stoles, but to students, teachers, administrators, parents, drivers, engineers, and custodians. The move to college becomes one more picture of this calling, since a new place and a new season also become a place to bear witness to Christ.

The prayer over students and school workers asks that each calling become a place where the gospel is shown and spoken. The custodian image keeps the point grounded: the most important person in the school may be the one who makes sure there is a place to learn. God has uniquely gifted each person, by the very creation each person is, to proclaim that there is a God who is for them, and that Jesus is the Messiah.

Key Takeaways

1. Confession names the living Christ Jesus’ question does not merely ask for information. The question draws out the heart’s allegiance and asks whether Jesus is only one voice among many, or the “I am” standing before the disciples. Peter’s confession becomes the place where faith speaks plainly: Jesus is the Messiah, the Son of the living God. [38:25]
2. The rock is the confession Peter receives a blessing, but the weight falls on what Peter says about Christ. The church is built where Jesus is confessed as the One who comes in flesh and blood, dies, rises, and gives life. A community loses its footing when personality, program, or history replaces that confession as the foundation. [39:33]
3. Ordinary care becomes holy witness Changing diapers, opening classrooms, teaching lessons, and welcoming children are not small things when done as part of God’s care for the world. The gospel is not only announced in formal religious moments, but also embodied in patient, practical love. A child can learn that God is for them before that child has words to explain it. [37:07]
4. Every vocation carries gospel purpose Romans names gifts that differ, and that difference is grace, not hierarchy. Teaching, encouraging, leading, giving, showing compassion, and doing quiet work all become ways of proclaiming who Christ is. The stole is not the sign that a person may witness, because baptism and calling already send the Christian into daily places. [43:18]
5. Hidden roles hold sacred weight The custodian image refuses to measure importance by visibility. A clean, safe, ready space can become the condition for learning, community, and care. God’s work often moves through the people whose labor is noticed least, yet whose faithfulness holds the whole thing together.

Bible Reading

Matthew 16:13-16
“Now when Jesus came into the district of Caesarea Philippi, he asked his disciples, ‘Who do people say that the Son of Man is?’ And they said, ‘Some say John the Baptist, others say Elijah, and others Jeremiah or one of the prophets.’ He said to them, ‘But who do you say that I am?’ Simon Peter replied, ‘You are the Christ, the Son of the living God.’” [38:25]

Romans 12:6-8
“Having gifts that differ according to the grace given to us, let us use them: if prophecy, in proportion to our faith; if service, in our serving; the one who teaches, in his teaching; the one who exhorts, in his exhortation; the one who contributes, in generosity; the one who leads, with zeal; the one who does acts of mercy, with cheerfulness.” [42:59]

Exodus 3:14
“God said to Moses, ‘I AM WHO I AM.’ And he said, ‘Say this to the people of Israel: “I AM has sent me to you.”’” [38:04]

Observation questions

In Matthew 16, what different answers do people give about who Jesus is, and how is Peter’s answer different from the others? [39:07]
What ordinary acts of care are described as witness, and what do those actions show about God and God’s people? [37:38]
In Romans 12:6-8, what kinds of gifts and roles are named, and what do they have in common? [43:06]
What examples are given of people in different school-related callings who can bear witness to Christ? [43:54]

Interpretation questions

Jesus asks, “Who do you say that I am?” Why does that question reach deeper than simply asking for correct information about Jesus? [38:33]
Peter is called blessed after confessing Jesus as the Messiah. What does it mean to say that the church is built on that confession rather than on a personality, title, or visible position? [39:33]
God reveals himself as “I AM” in Exodus, and Jesus asks, “Who do you say that I am?” How does that connection sharpen what Peter is really confessing about Jesus? [38:52]
Romans says gifts differ according to grace. How might that change the way a group sees “important” work versus “small” work in a church, school, or home? [44:18]

Application questions

Jesus still asks, “Who do you say that I am?” When that question becomes personal, what answer is most natural on the lips, and what answer is actually shaping daily life right now? [38:48]
Ordinary care can become holy witness. Where might patient, practical love need to become more intentional this week at home, at school, at work, or in the neighborhood? [37:21]
Every vocation can become a place to show and speak the gospel. In what setting does it feel easiest to witness to Christ, and in what setting does it feel hardest? Why? [40:19]
Many people carry out hidden work that makes life possible for others. Who is a “custodian kind of person” in daily life whose quiet faithfulness often goes unnoticed, and how could that person be honored this week? [44:22]
God gives gifts that differ. Which gift in Romans 12 seems closest to how God has shaped this life right now: serving, teaching, encouraging, giving, leading, or showing mercy? What would it look like to use that gift more freely? [42:59]
A building is meant to be used, worn out, and filled with life. What spaces, routines, or relationships have become too guarded or too tidy to welcome others well? [37:01]
There is a God who is for his people, and Jesus is the Messiah. Who might especially need to receive that hope in the coming school year, and what could a simple, faithful witness to that person look like? [44:51]

46s

“My interpretation, the interpretation I was taught is when Jesus says, you are Peter, and on this rock, I will build you by a church. Well, yeah, obviously, the word petros in Greek is rock. Right? So there's a there's connections there. But the confession of Peter is what the rock is. The rock of the faith is who do you say that I am? And we say, you are the Messiah, the son of the living God. That you have come to us in flesh and blood to be with us, to live, to die, to rise so that we can have life and hope. Who do you say that I am? The rock is our confession.”

61s

“And that's what Paul was saying when he was writing to the Romans. Right? We're all called to different things. We have gifts that differ and in grace given to us, prophecy and proportion of faith, minister and minister and teachers and teaching, encouragers and encouragement, the giver and sincerity, the leader and diligence, the compassionate and cheerfulness. we know who Jesus is, when we, like Peter, can say, you are the Messiah, the Son of the God, when he asks, who who do they say I am? We say, you are I am. You are the son of the living God. You are part of the Trinity. You are our salvation and our life. And through you, we are blessed in the waters of baptism and giving gifts to live and proclaim the good news. And you don't have to wear a stole to do it. You can do it wherever you are called to be.”

51s

“It's there to be worn out. It's there to be have kids playing and enjoying and learning and growing and hearing in this sanctuary to have them come and to do chapel and to be present in this space and understand this is for them, that God is for them. And they can hear that gospel message in the way that you give witness, in the way that you care, even in the way that you change diapers, which I know is not probably anybody's favorite activity. I'm done I'm done with that stage in my house, and you know what? I don't miss it. But how we care for those who are put in our midst is a witness to who we believe God is and who we believe we are to be as God's people.”
