God can do everything but he will not do anything that contradicts His character.

Are there some things God cannot do? Some Christian preachers take pride in preaching such a “sermon”, listing things that God can’t do viz., God can’t stop loving people; God can’t remember our sins; God can’t stop thinking about His children and so on. They are trying to sound wiser than God, are advocates of God and are trying to add to the glory of God by preaching such things. Foolishness! For with God nothing shall be impossible. – Luke 1:37. While God can do everything, He will not do these (and many other things that contradicts His nature) by deliberate choice and determined will. For example, He will not remember our sins anymore after He has forgiven them – not that He can’t. He is not a human being with a weakness to forget things. He is not suffering from amnesia!
