For I give you to understand, brethren, that the gospel which was preached by me is not according to man. 12For neither did I receive it of man: nor did I learn it but by the revelation of Jesus Christ. 13For you have heard of my conversation in time past in the Jews' religion: how that, beyond measure, I persecuted the church of God and wasted it. 14And I made progress in the Jew's religion above many of my equals in my own nation, being more abundantly zealous for the traditions of my fathers. 15But when it pleased him who separated me from my mother's womb and called me by his grace, 16To reveal his Son in me, that I might preach him among the Gentiles: immediately I condescended not to flesh and blood. 17Neither went I to Jerusalem, to the apostles who were before me: but I went into Arabia, and again I returned to Damascus. 18Then, after three years, I went to Jerusalem to see Peter: and I tarried with him fifteen days. 19But other of the apostles I saw none, saving James the brother of the Lord. 20Now the things which I write to you, behold, before God, I lie not. 21Afterwards, I came into the regions of Syria and Cilicia. 22And I was unknown by face to the churches of Judea, which were in Christ: 23But they had heard only: He, who persecuted us in times past doth now preach the faith which once he impugned. 24And they glorified God in me.
