Galatians 1:14 (KJV)

As we said before, so say I now again, if any man preach any other gospel unto you than that ye have received, let him be accursed.

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:

But when it pleased God, who separated me from my mother's womb, and called me by his grace,

To reveal his Son in me, that I might preach him among the heathen; immediately I conferred not with flesh and blood:

Neither went I up to Jerusalem to them which were apostles before me; but I went into Arabia, and returned again unto Damascus.

Then after three years I went up to Jerusalem to see Peter, and abode with him fifteen days.

But other of the apostles saw I none, save James the Lord's brother.
