Galatians 1:10-14

For do I now persuade men, or God? or do I seek to please men? for if I yet pleased men, I should not be the servant of Christ.

But I certify you, brethren, that the gospel which was preached of me is not after man.

For I neither received it of man, neither was I taught it, but by the revelation of Jesus Christ.

For ye 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:

And profited in the Jews’ religion above many my equals in mine own nation, being more exceedingly zealous of the traditions of my fathers.
