It was in obedience to a revelation that I went; and I laid before the Apostles the Good News that I am proclaiming among the Gentiles. I did this privately before those who are thought highly of, for fear that I might possibly be taking, or might have already taken, a course which would prove useless.

For if I build up again those things which I destroyed, I prove myself a transgressor.

But let every man prove his own work, and then shall he have rejoicing in himself alone, and not in another.
