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.
