Now I want you to know, brothers, that the gospel preached by me is not of human origin. For I did not receive it from a human being, nor was I taught it, but it came through a revelation of Jesus Christ. For you heard of my former way of life in Judaism, how I persecuted the church of God beyond measure and tried to destroy it, and progressed in Judaism beyond many of my contemporaries among my race, since I was even more a zealot for my ancestral traditions. But when (God), who from my mother’s womb had set me apart and called me through his grace, was pleased to reveal his Son to me, so that I might proclaim him to the Gentiles, I did not immediately consult flesh and blood, nor did I go up to Jerusalem to those who were apostles before me; rather, I went into Arabia and then returned to Damascus. Then after three years I went up to Jerusalem to confer with Kephas and remained with him for fifteen days. But I did not see any other of the apostles, only James the brother of the Lord.
”Amen, amen, I say to you, whoever does not enter a sheepfold through the gate but climbs over elsewhere is a thief and a robber. But whoever enters through the gate is the shepherd of the sheep. The gatekeeper opens it for him, and the sheep hear his voice, as he calls his own sheep by name and leads them out. When he has driven out all his own, he walks ahead of them, and the sheep follow him, because they recognize his voice. But they will not follow a stranger; they will run away from him, because they do not recognize the voice of strangers.” Although Jesus used this figure of speech, they did not realize what he was trying to tell them.
So Jesus said again, “Amen, amen, I say to you, I am the gate for the sheep. All who came [before me] are thieves and robbers, but the sheep did not listen to them. I am the gate. Whoever enters through me will be saved, and will come in and go out and find pasture.”
