Fallen man is free to choose what he desires, but because his desires are only wicked he lacks the moral ability to come to Christ. As long as he remains in the flesh, unregenerate, he will never choose Christ. He cannot choose Christ precisely because he cannot act against his own will. His fall is so great that only the effectual grace of God working in his heart can bring him to faith.
R. C. SproulGod not only initiated my salvation, He not only sowed the seed, but He made sure that that seed germinated in my heart by regenerating me by the power of the Holy Ghost.
