Galatians 1:13-16 NIV

[13] For you have heard of my previous way of life in Judaism, how intensely I persecuted the church of God and tried to destroy it. [14] I was advancing in Judaism beyond many of my own age among my people and was extremely zealous for the traditions of my fathers. [15] But when God, who set me apart from my mother’s womb and called me by his grace, was pleased [16] to reveal his Son in me so that I might preach him among the Gentiles, my immediate response was not to consult any human being.
