Q87

What is repentance unto life?

Repentance unto life is a saving grace180, whereby a sinner, out of a true sense of his sin, and apprehension of the mercy of God in Christ181, doth, with grief and hatred of his sin, turn from it unto God182, with full purpose of, and endeavor after, new obedience183.
