A believer hasn't got any fellowship with unbeliever. A crow and a dove cannot talk together. A crow eat on an old dead carcass. A dove is one bird without a gall. If it'd eat that dead carcass, it'd kill it. It's a special built bird, a--a dove is. A dove only eats grain. He has no gall. He could not digest it. So is the Christian, has no gall of bitterness in them. They cannot eat the things of the world. A crow could eat the things, wheat, and he can also eat carcass. He's a hypocrite.
And a dove, I want to tell you something... A dove does not have to find water for a bath. Did you ever pick up a little dove, rub your hand over him? He's oily. There's something from the inside comes out and keeps him clean. Oh, my. His body's oiled, from a oil from the inside coming out. Amen. I don't want to get started on that; I'll get off my subject. But he keeps his body, his feathers, his garments clean by an inside oil. Every time he works his body, that works up there on his feathers and keeps him perpetually, all the time, clean. Oh, the Blood of Jesus Christ sanctifies the believer day and night.
