But if a wicked person turns away from all the sins they have committed and keeps all my decrees and does what is just and right, that person will surely live; they will not die. None of the offenses they have committed will be remembered against them. Because of the righteous things they have done, they will live. Ezekiel 18:21-22
God, who knows all things, can and does choose to forget. God does not remember our sins when we turn to him. Does he fail to recall the wrongs we have done? Is there a lapse in one who knows what has been, what is, and what will be? That is not the case at all. God chooses not to reference or to entertain these pass events.
