Cross Fit Summer Series Devotional
Each week, we’ll explore a core truth about our faith—paired with scripture, reflection, discussion questions, and simple family activities. These devotionals are designed to help you grow stronger in your walk with Christ, together as a household.
Note: Each campus is rotating through the CrossFit sermon topics on a slightly different schedule, so the weekly devotional may not always match the message you hear on Sunday at Foundry. That’s okay! Over the course of the series, every major theme will be covered in both the sermons and devotionals—helping us all grow closer to Christ together as one church family.

Big Idea: Just like you can’t build muscle without effort, you can’t grow spiritually without sound doctrine.
Knowing about God isn’t just for pastors or scholars—it’s for everyone who wants to grow in faith. Jesus said the greatest commandment is to love God with all our heart, soul, mind, and strength (Mark 12:30). That includes our mind! Loving God means thinking rightly about who He is—and that takes effort.
Just like an athlete has to train with purpose, we grow spiritually when we put in the work to know what the Bible says and why it matters. Without a foundation of sound doctrine, our faith can become shallow or confused. But when we study God’s Word carefully, we get to know the real God—not just who we imagine Him to be. Right belief leads to right living.
Hebrews 5:14 says that mature believers have “their powers of discernment trained by constant practice.” That’s theology in everyday life! Sound doctrine helps us tell truth from error, gives us confidence when we pray, and shapes how we live. It’s not always easy to dig deep into Scripture or wrestle with hard questions, but that effort produces lasting strength.
Think about it: You wouldn’t build a house without a solid foundation. In the same way, we shouldn’t try to build our lives without true beliefs about God. Theology isn’t just abstract—it’s deeply practical. It helps us forgive, love others, resist temptation, and walk in hope.
Family Activity Options:
Option 1: All Ages – Do a short workout together (pushups, planks, etc.). Then talk about how training your body takes effort—and how training your mind in God's truth helps your faith grow.
Option 2: Young Children – Show two building blocks: one solid and one wobbly. Use them to explain how a strong foundation (truth about God) helps us stand strong.
Option 3: Teens – Look up a verse together (like Titus 1:9 or 2 Timothy 3:16). Talk about why knowing the Bible matters when you face tough decisions or questions from friends.
Discussion Question: Why do you think it matters what we believe about God? Can you think of a time when knowing the truth helped you make a wise choice?
Prayer:
Dear God, thank You for giving us Your Word to teach us what’s true. Help us to grow in our knowledge of You so we can grow in our faith. When it’s hard to understand or stay consistent, give us strength to keep going. Teach us to love You with all our minds as well as our hearts. In Jesus’ name, Amen. -
Big Idea: God isn’t far away – He is with us through the Holy Spirit. Jesus promised to send a Helper, the Holy Spirit, to be with us forever (John 14:16). The Holy Spirit is God living in the hearts of believers. We can’t see Him, but we feel His work in us – like feeling the wind even though we can’t see air. The Spirit comforts us when we’re sad, gives us courage to do what’s right, and helps us understand God’s Word. God’s own Spirit is with us every moment!
Because of the Holy Spirit, we are never alone. Maybe you’ve felt a quiet nudge to do the right thing or felt peace while praying about something scary – that’s the Holy Spirit at work, God with us and in us.
Family Activity Options:
Option 1: All Ages – Close your eyes and feel a breeze or a fan blowing on your skin. Talk about how you can feel the wind even if you can’t see it – like sensing the Holy Spirit’s presence even though He is invisible.
Option 2: Young Children – Draw a small flame to represent the Holy Spirit, and explain that at Pentecost God’s Spirit appeared as little flames (Acts 2). Hang the picture as a reminder that the Holy Spirit is always with us.
Option 3: Teens – Spend a few minutes in silent prayer asking the Holy Spirit to speak to you. Afterwards, share if you felt comfort, a new thought, or a Bible verse come to mind, and discuss how the Holy Spirit might be guiding you.
Discussion Questions:
Can you think of a time when you felt God’s comfort or a “nudge” to do the right thing?
How does knowing the Holy Spirit is with you make a difference in your daily life?
Prayer: Heavenly Father, thank You for giving us Your Holy Spirit. We’re grateful that we are never alone because You live in our hearts. Please guide and strengthen us by Your Spirit each day. In Jesus’ name, Amen.ription

We believe in one God who is three Persons: Father, Son, and Holy Spirit. This holy mystery is called the Trinity. There is only one God, but He exists as Father, Son, and Spirit together. The Bible gives us a glimpse: when Jesus was baptized, the Father spoke from heaven and the Holy Spirit came down like a dove while Jesus the Son was in the water (Matthew 3:16-17). All three were present at the same time – yet it was one God!
We may not fully understand how God can be three-in-one, and that’s okay. God is greater than we can imagine. The Trinity shows us that God is all about loving relationship, and He even invites us into that love. The Father made us, the Son saved us, and the Holy Spirit lives in and among us – we experience God in these three wonderful ways. We can praise Him for being so great and mysterious, yet so near!
Family Activity Options:
Option 1: All Ages – Braid three strands of yarn (or rope) into one cord. Each strand stays itself, but together they form one cord – like Father, Son, and Spirit are distinct yet one God. Hang up the braided cord as a reminder of our three-in-one God.
Option 2: Young Children – Draw a triangle and label the corners Father, Son, Holy Spirit. It has three corners but is one triangle – a simple picture of the Trinity. Thank God for being three-in-one and caring for us.
Option 3: Teens – Have each person name one thing they appreciate about God the Father, God the Son, and God the Holy Spirit. Then pray together, thanking Father, Son, and Spirit for who He is and what He has done.
Discussion Questions:
How would you explain the Trinity in your own words?
Why is it special that God is Father, Son, and Holy Spirit?
Prayer: Almighty God—Father, Son, and Holy Spirit—we praise You as the one true God. Thank You, Father, for creating us; Jesus, for rescuing us; and Holy Spirit, for helping us every day. Draw us closer to You each day. Amen.

Core Focus: Perseverance in faith and sanctification
Big Idea: Following Jesus isn’t a sprint; it’s a lifelong journey. The Holy Spirit patiently trains us to become more like Christ day by day.Growing Toward Christlikeness
Sanctification is God’s gracious work of shaping us into the image of His Son (Romans 8:29). Because Jesus already secured our salvation, we run this “race” from a place of acceptance, not anxiety. The writer of Hebrews invites us to “run with endurance … fixing our eyes on Jesus” (Hebrews 12:1-2). The finish line isn’t a checklist—it’s Christ Himself.
Think of it less as gritting your teeth through a grueling workout and more as a gardener tending a beloved plant: daily sunlight, steady watering, careful pruning. Over time the plant becomes strong and fruitful. Our cooperation with the Spirit—through Scripture, prayer, worship, and obedience—creates the conditions for steady, joyful growth. We may feel growing pains, yet every “rep” the Spirit leads us through forms humility, faith, and love.
Philippians 2 reminds us of the beautiful tension: “Work out your own salvation … for it is God who works in you” (vv. 12-13). We exert effort, but the power comes from Him. Sanctification isn’t drudgery; it’s the Spirit’s invitation to participate in the life of Jesus, learning to think, act, and love the way He does.
Family Activity Options:
Option 1: All Ages – Cut a paper circle into rings like a tree trunk. Write a way God has grown each family member in the last year on successive rings. Look for ways to celebrate visible evidence of sanctification and thank God for it.
Option 2: Young Children – Plant a Seed – Start a bean in a clear cup. Watch roots and leaves appear over days. As you observe this growth remember that growth takes time but is certain when conditions are right.
Option 3: Teens – Draw a personal timeline marking moments God used to grow you (camp, hard class, friendship, Scripture). Reflect on how God weaves ordinary and difficult moments into spiritual maturity.
Discussion Questions:
What’s one area of your life where you’ve seen spiritual growth this year?
What’s something you find hard right now that might be part of your spiritual endurance training?

Big Idea: Everyone loves a good before-and-after transformation—Jesus offers the ultimate one!
Have you ever seen a makeover show or a house renovation where something broken-down becomes brand new? That’s a picture of what Jesus does in our lives—He doesn’t just rescue us from sin; He completely transforms us. Salvation isn’t just about being pulled out of danger—it’s about becoming someone new.
When we trust Jesus, we aren’t just forgiven; we’re made new (2 Corinthians 5:17). We move from being spiritually dead to alive, from lost to found, from enemies of God to beloved children. Jesus’ death and resurrection don’t only remove our sin—they also give us a brand-new identity. We are filled with His Spirit, given a new purpose, and called to live a new kind of life: one that reflects Jesus.
Think of it like this: if sin is like a dirty shirt we couldn’t take off, Jesus didn’t just wash it—He gave us brand-new clothes and welcomed us to live in His house as part of His family. Salvation changes everything (or at least it should)—how we think, how we love, and how we live.
We don’t earn this transformation by trying harder. It starts with faith, but it grows as we walk with Jesus. The more we know Him, the more we become like Him. This is salvation: not just a moment of rescue, but a lifetime of being made new.
Family Activity Options:
Option 1: All Ages – Find and share some fun "before-and-after" pictures (like baby photos vs. now, or a messy room cleaned up). Then ask: “What do you think a ‘before-and-after’ of someone’s heart might look like when they follow Jesus?” Talk about how Jesus doesn’t just clean us up—He gives us a new heart (Ezekiel 36:26).Option 2: Young Children – Use a toy that can “transform” (like a Transformer or LEGO build). Show how it starts one way but becomes something completely different. Say: “When we believe in Jesus, He changes our hearts and helps us become more like Him.”
Option 3: Teens – Have each person write down a word or phrase describing who they were before knowing Jesus or before a time they really started following Him. Then write a word that describes who they are now or who they are becoming in Christ. Share and discuss how Jesus is transforming each of you.
Discussion Questions:
How is being saved by Jesus more than just being rescued?
How have you seen Jesus transforming your life—or someone else’s?
Prayer:
Jesus, thank You for not just saving us from sin, but saving us into a new life. You are changing us from the inside out. Help us to keep becoming more like You. We trust that Your work in us isn’t done—You're still transforming us every day. Amen. -
Core Focus: The authority of the Bible
Big Idea: Fad diets come and go, but God’s Word is the real deal—it nourishes and sustains our faith for the long haul.Devotional Thought
Have you noticed how a “revolutionary” new diet seems to pop up every few months? Keto, paleo, juice cleanses—each promises quick results, yet most prove hard to maintain and leave us craving something more. In the same way, our culture offers spiritual “quick fixes”: inspirational quotes, self‑help trends, viral challenges. But only one source is proven, balanced, and life‑giving for every season—the Bible.
“All Scripture is God‑breathed and is useful for teaching, rebuking, correcting and training in righteousness, so that the servant of God may be thoroughly equipped for every good work.”
—2 Timothy 3:16‑17Because Scripture is God‑breathed, it carries unmatched authority. It isn’t a menu we pick and choose from; it is the full‑course meal God prepared to grow healthy, resilient disciples. When we feed daily on His Word, we gain steady energy for obedience, spiritual muscle for trials, and the joy that comes from real nourishment—not empty calories.
So before we reach for the next spiritual “snack,” let’s pull up a chair to the feast God has already set.
Family Activity Options
Option 1 – All Ages: Build a Balanced Plate
Spread out pictures or actual samples of different foods: proteins, veggies, fruit, sweets. Invite everyone to assemble a balanced meal on a paper plate, then compare it with a plate made only of candy.
Discuss: Which plate fuels your body long‑term? Now create a spiritual plate: Scripture, prayer, worship, serving. Which “food group” is foundational? How does the Bible keep the other practices healthy?Option 2 – Young Children: Taste Test & Treasure Verse
Offer a tiny piece of candy and a slice of fresh fruit. After tasting both, ask which one helps their body grow strong. Hide a slip of paper with Matthew 4:4 (“People do not live on bread alone, but on every word that comes from the mouth of God”) and let the kids hunt for the “daily bread” verse. Decorate a bookmark with the verse to keep in their Bible.Option 3 – Teens: Label Reading & Scripture Meal‑Prep
Grab a few packaged snacks and read the ingredient lists together—notice the fillers and additives. Then read Acts 17:11 and talk about “checking the label” of ideas you hear online by comparing them with Scripture. Challenge each teen to design a one‑week “Scripture meal‑prep” plan (passage + time of day) and support one another in sticking with it.Discussion Questions
How does knowing the Bible is God‑breathed change the way we approach it?
What practical rhythms can our family adopt so that Scripture becomes our daily diet, not an occasional snack?
Prayer
Father, thank You for giving us Your Word—the only diet that truly works. Help us crave the Scriptures like daily bread, trust their authority over every other voice, and find lasting strength in Your truth. Nourish our hearts so we can live out Your purposes. In Jesus’ name, Amen.
