Grace works ahead of us to draw us toward faith, to begin its work in us. Even the first fragile intuition of conviction of sin, the first intimation of our need of God, is the work of preparing, preventing grace, which draws us gradually toward wishing to please God. Grace is working quietly at the point of our desiring, bringing us in time to despair over our own unrighteousness, challenging our perverse dispositions, so that our distorted wills cease gradually to resist the gift of God.
