What does repent mean? To weep that you have done something wrong? No; that is all very well, but that is not repentance. Is repentance to be vexed with yourself that you have fallen away from your own idea…? No; that is not repentance. What is repentance? Turning your back upon the evil thing; pressing on to lay hold of that for which Christ laid hold upon you. To repent is to think better of it, to turn away from the evil. No man is ever condemned for the wicked things that he has done; he is condemned because he won’t leave them.
