“For He Himself knows our frame; He is mindful that we are but dust.” (Psalm 103:14 NASB).
Do we sin? Yes.
Do we love to sin? No true believer does; we hate it.
Why? Because God chose, in His love and mercy, to give us a new heart. Before our rebirth, we were attracted only to the things of this world; we were lovers of 'self,' not of God. Yet, when God was pleased to reveal His Son in us, Christ’s life began to spread His own heart’s desire within us. And bit by bit, we discover that He is attracted, not toward the evil that we once were attracted to, but toward righteousness. We have Christ, the very glory of God, in us. Yet God knows our frame. He knows we are but dust. (Psalm 103:14). We are still the fleshly clay pot, which is relentlessly set in opposition to the Spirit. (Galatians 5:17). But God dwells within us and opposes the flesh. He protects us, sometimes even from what we think we want to do.
“You are from God, little children, and have overcome them; because greater is He who is in you than he who is in the world.” (1 John 4:4 NASB).
Grace means that God within us opposes the desires of our flesh and draws us to Himself.
