You don't see crows and doves dwelling together, because they don't have no fellowship. They don't have things in common. The crow can fly on a dead carcass and eat it. And... But the dove will go to the wheat field and eat the grain. Now, I want you to notice what the devil can do. Now, the dove cannot set on the dead carcass and eat. But the crow can eat the dead carcass and also eat the wheat. He's a hypocrite. See? The dove can't do it, because her makeup is different.
Now, a person can impersonate Christianity, but a Christian can't impersonate sin. The Spirit that's in him won't let him do it. He has... The dove, the reason she couldn't eat that, it would kill her. She had no gall, as we spoke the other night. She has no gall. If she'd eat it, it would kill her; the poison would kill her. She can't do it.
But the crow can both eat the dead carcass and the wheat also. So that's what an impersonator can do. But a real genuine Christian can be nothing else but a pure article of God.
