Mark 3:25-30

and a fragmented household will not be able to stand, for it is divided. And if Satan fights against himself he will not endure, and his end has come.” Jesus said to them, “Listen. No one is able to break into a mighty man’s house and steal his property unless he first overpowers the mighty man and ties him up. Then his entire house can be plundered and his possessions taken. I tell you this timeless truth: All sin will be forgiven, even all the blasphemies that are spoken. But there can never be forgiveness for the one who blasphemes against the Holy Spirit, for he is guilty of an eternal sin!” (This is because they said he was empowered by a demon spirit.)
