Satan is your accuser. He has all the dirt on you. He knows what you did. And what if he told your church or your friends what you’ve done? That little secret you try to keep hidden from everyone, even from God. Satan knows about it. Satan has a dirt-file on you, and he will not let you forget the fact.
