Chris has already done a great job of covering this, so for many of you this post will be moot. However, I did my own study of Repentance in the Bible too and I noticed something!
Now I understand how many have made the mistake of thinking that repent means "to turn"! It's because God also commanded to turn from sin as well. In three out of the following four passages (there are many more) we find the phrases "repent" AND "turn":
But if the wicked will turn from all his sins that he hath committed, and keep all my statutes, and do that which is lawful and right, he shall surely live, he shall not die. Ezekiel 18:21
But shewed first unto them of Damascus, and at Jerusalem, and throughout all the coasts of Judaea, and then to the Gentiles, that they should repent and turn to God, and do works meet for repentance. Acts 26:20
And if he trespass against thee seven times in a day, and seven times in a day turn again to thee, saying, I repent; thou shalt forgive him. Luke 17:4
And finally:
Who can tell if God will turn and repent, and turn away from his fierce anger, that we perish not?
10 And God saw their works, that they turned from their evil way; and God repented of the evil, that he had said that he would do unto them; and he did it not. Jonah 3:9-10!
