John 10:1-7

“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. But he who enters by the door is the shepherd of the sheep [the protector and provider]. The doorkeeper opens [the gate] for this man, and the sheep hear his voice and pay attention to it. And [knowing that they listen] he calls his own sheep by name and leads them out [to pasture]. When he has brought all his own sheep outside, he walks on ahead of them, and the sheep follow him because they know his voice and recognize his call. They will never follow a stranger, but will run away from him, because they do not know the voice of strangers.” Jesus used this figure of speech with them, but they did not understand what He was talking about. So Jesus said again, “I assure you and most solemnly say to you, I am the Door for the sheep [leading to life].
