John 10:1, 9

“I assure you and most solemnly say to you, he who does not enter by the door into the sheepfold, but climbs up from some other place [on the stone wall], that one is a thief and a robber.

I am the Door; anyone who enters through Me will be saved [and will live forever], and will go in and out [freely], and find pasture (spiritual security).
