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.
