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 of mine.
