Galatians 1:15-19

But when God, who had chosen me and set me apart before I was born, and called me through His grace, was pleased [Is 49:1; Jer 1:5] to reveal His Son in me so that I might preach Him among the Gentiles [as the good news—the way of salvation], I did not immediately consult with anyone [for guidance regarding God’s call and His revelation to me]. Nor did I [even] go up to Jerusalem to those who were apostles before me; but I went to Arabia and stayed awhile, and afterward returned once more to Damascus. Then three years later I did go up to Jerusalem to get acquainted with Cephas (Peter), and I stayed with him fifteen days. But I did not see any other apostle except James, the [half] brother of the Lord.
