John 10:7, 9 Then said Jesus unto them again, Verily, verily, I say unto you, I am the door of the sheep. … I am the door: by me if any man enter in, he shall be saved, and shall go in and out, and find pasture.

Psalm 118:19-21 Open to me the gates of righteousness: I will go into them, and I will praise the LORD: This gate of the LORD, into which the righteous shall enter. I will praise thee: for thou hast heard me, and art become my salvation.
