I do not deny that God does evil. However, This does NOT stain the character of God in any way, it merely accentuates his righteousness in judgment, as you will see. The scripture says, “God repented of the evil which he thought to do”. God was going to do evil? What was the evil he was about to do? He was going to destroy (Exodus 32:10) the children of Israel after they made stone calves and claimed that the calves where the actual ones that freed them from Egypt’s tyranny. As the context says, “They corrupted themselves.” (Exodus 32:7).
Ask yourself now, what is punishment? It is the action that fulfills justice. To the one receiving it, it is evil (corrupting or destroying the good that they are, or the good that they have achieved in their lives, or the peace they gained). To the one administering the punishment (evil) it is either the satisfaction of justice or the tool to bring proper behavior back. Indeed, when we all stand before God in the end, the ones who have rejected him will experience great evil (punishment), and from God’s perspective, justice will be satisfied.
The key here is that when man does evil, it is rebellion against God and the good things he made. When God does evil, it is punishment and the satisfaction of righteous judgment. It’s silliness to think that God is rebelling against himself or corrupting himself. God’s evil is the action of perfect judgment. Against it, none of us can stand.
However, Jesus’ death satisfied the righteous judgment of God upon every man so that peace could exist between them if man chooses it.
