What did the Lord say in Ezekiel 18:21-23?

"But if a wicked man turns away from all the sins he has committed and keeps all my decrees and does what is just and right, he will surely live; he will not die. None of the offenses he has committed will be remembered against him. Because of the righteous things he has done, he will live. Do I take any pleasure in the death of the wicked? declares the Sovereign LORD. Rather, am I not pleased when they turn from their ways and live?
