The day when God reveals himself to the world will be the last day of the world. For a part cannot contain the whole. And God's love is also manifested in the fact that he does not reveal himself to us. The Devil is also a former angel, a creation of God. And he performs the function given to him by God. He does not tempt people to distract them from God. The Devil also has a hard time, because he is blamed for everything. And maybe he is just a tired angel. God will never punish him, because he loves the Devil too.
