Grace destroys the disposition to resist.
We then see, and desire, as we ought. And in doing so, we turn from sin and toward God.
Before the grace of God gives us this new birth, we are as Lazarus in the tomb. When the call comes, we awake--realize we are in the dark, surrounded by death, disease, and decay--we realize we no longer belong there, and freely leave our self-made tomb to come to Christ--we come then to the light of day, to fresh air, to new life, to the presence of Christ. We leave behind the gravecloths.
But we cannot "freely choose" something that is contrary to our own will.
The curse reversed our ethical "polarity" such that we are pointed due South, away from God. We hate God. We repress the clear revelation of him in creation and conscience. But then, the grace of God--far from "forcing the needle Northward"--supernaturally changes the very nature of our "magnet," reversing our polarity such that we "by nature" begin to point due North again.
This *monergistic regeneration* (to insert a terminological shortcut in order to save a paragraph long explanation) results in repentance and faith. It is, first to last, a gift of God. We contribute nothing--therefore God gets all the glory (Soli Deo Gloria!).
