The good news of the gospel is not that God gives you a list of rules to follow or tells you to try harder to manage your emotions. The good news is that God transforms you from the inside out. He gives you a new heart.
This transformation happens in the same three dimensions where sin corrupted your heart. God transforms your thinking through His Word. As you meditate on Scripture and preach truth to yourself, the Holy Spirit renews your mind. You begin to think God’s thoughts, to believe what He says about Himself, about you, and about your circumstances.
God transforms your desires. Psalm 37:4 says that as you delight in the Lord, He gives you the desires of your heart. This doesn’t mean He grants whatever you want like a cosmic vending machine. It means that as you treasure Christ, He changes what you want. You start desiring what He desires. You start treasuring what He treasures. And as your desires change, your emotions follow.
God transforms your will. Philippians 2:13 tells us that God works in us both to will and to work for His good pleasure. He doesn’t just change what you think and want. He enables you to actually do what He calls you to do. You make different choices because your heart has been changed.
This transformation is progressive. You’re not instantly fixed the moment you become a Christian. But God is faithful to complete the work He’s begun in you. And as you guard your heart with vigilance, asking those diagnostic questions when strong emotions arise (What am I believing? What am I wanting? What am I choosing?), you cooperate with the Spirit’s transforming work.
