Galatians 1:14-16

And [you have heard how] I surpassed many of my contemporaries among my countrymen in [my advanced study of the laws of] Judaism, as I was extremely loyal to the traditions of my ancestors. 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].
