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

7 Therefore Jesus said to them again, Truly, truly, I say to you, I am the door of the sheep.
9 I am the door. If any man shall enter by me, he shall be saved; and he shall go in, and shall go out, and he shall find pastures.
14 I am a good shepherd, and I know my sheep, and my sheep know me.
