Galatians 1:10-14

10For do I now persuade men, or God? Or do I seek to please men? For if I still pleased men, I would not be a bondservant of Christ.

11But I make known to you, brethren, that the gospel which was preached by me is not according to man.

12For I neither received it from man, nor was I taught it, but it came through the revelation of Jesus Christ.

13For you have heard of my former conduct in Judaism, how I persecuted the church of God beyond measure and tried to destroy it.

14And I advanced in Judaism beyond many of my contemporaries in my own nation, being more exceedingly zealous for the traditions of my fathers.
