John 10:7; John 10:9; John 10:14

7 Then said Jesus unto them again, "Verily, verily I say unto you, I am the door of the sheep.
9 I am the door; by Me if any man enter in, he shall be saved, and shall go in and out, and find pasture.
14 I am the Good Shepherd, and know My sheep and am known by Mine.
