Over 30+ years as a disciple of Jesus Christ, I’ve attended several churches and noticed a pattern that often goes unaddressed—whether intentional or not. I call it “The Back Door Theory.”
Churches pour energy into behaviors: “Do x, y, and z. Never do e, f, or g.” The New Testament is full of ethical commands, so that focus makes sense on the surface. But the dynamic frequently presented is:
“Righteous people behave this way.”
“Therefore, if we behave this way, we’ll be righteous.”
What gets missed is critical:
Righteous people don’t become righteous by behaving rightly.
Righteous people behave rightly because they are righteous through their relationship with Christ.
That relationship transforms them from the inside out.
Simply mimicking behavior doesn’t produce righteousness. Trying to enter through the “back door” of conduct—rather than through mindset renewal—misses the heart of transformation. This isn’t always taught overtly, and I’m not accusing leaders of malice. But by not equipping disciples with tools to participate in God’s renewing work, the result is exactly what we see: saved people who still live defeated.
Mindset is central, and it’s overlooked in the American Church. Consider
Matthew 15:19–20:
“For out of the heart come evil thoughts, murder, adultery, sexual immorality, theft, false witness, slander. These are what defile a person. But to eat with unwashed hands does not defile anyone.”
Jesus is directly confronting the religious leaders’ obsession with external behavior (washing hands). He says defilement originates in the heart—the seat of the mind, will, and moral compass—not in outward actions. The heart drives the behavior, not the other way around.
What does this mean for discipleship? Everything.
Your mindset drives your behavior. You can wash your hands (a “righteous” act in 1st-century Judea), but that doesn’t reveal the state of your heart. Alignment must start inside—mindset set on God—then flow outward.Paul prays for this exact dynamic.
Colossians 1:9–10:
“And so, from the day we heard, we have not ceased to pray for you, asking that you may be filled with the knowledge of his will in all spiritual wisdom and understanding, so as to walk in a manner worthy of the Lord, fully pleasing to him: bearing fruit in every good work and increasing in the knowledge of God.”
Knowledge of God’s will, spiritual wisdom, and understanding (mindset) come first. Worthy walking and fruit-bearing (behavior) follow as the natural result.
I haven’t given you a single “smoking gun” verse that says “mindset drives behavior.” That’s intentional. Biblical truth often surfaces through themes and principles, not isolated proof-texts. This is why biblical familiarity is foundational: repeated exposure to Scripture reveals recurring patterns and concepts.
So, is mindset—renewing the mind to align with who God is—a discipleship issue? Absolutely. It may be the discipleship issue.
Buckle up, men. Time to work on our mindsets. Bearing fruit and pleasing the Lord are what’s at stake.
