John 10:3-10

To him the porter openeth; and the sheep hear his voice: and he calleth his own sheep by name, and leadeth them out. When he hath put forth all his own, he goeth before them, and the sheep follow him: for they know his voice. And a stranger will they not follow, but will flee from him: for they know not the voice of strangers. This parable spake Jesus unto them: but they understood not what things they were which he spake unto them. Jesus therefore said unto them again, Verily, verily, I say unto you, I am the door of the sheep. All that came before me are thieves and robbers: but the sheep did not hear them. I am the door; by me if any man enter in, he shall be saved, and shall go in and go out, and shall find pasture. The thief cometh not, but that he may steal, and kill, and destroy: I came that they may have life, and may have it abundantly.
