In saving sinners, the Spirit does not supersede the normal processes of thought and choice. He does not overcome the sinner, but transforms him. The Spirit irresistibly draws the elect to Himself with lovingkindness and omnipotence (Jer. 31:3; Hos. 11:4; Luke 14:23). This, then, is the amazing truth of God’s grace: God makes the will willing to will God in response to His call. That amounts to what theologians call effectual calling.
