12 For indeed I did not receive it from man, nor was I taught it, but [it came to me] through a [direct] revelation [given] by Jesus Christ (the Messiah).
13 You have heard of my earlier career and former manner of life in the Jewish religion (Judaism), how I persecuted and abused the church of God furiously and extensively, and [with fanatical zeal did my best] to make havoc of it and destroy it.
14 And [you have heard how] I outstripped many of the men of my own generation among the people of my race in [my advancement in study and observance of the laws of] Judaism, so extremely enthusiastic and zealous I was for the traditions of my ancestors.
15 But when He, Who had chosen and set me apart [even] before I was born and had called me by His grace (His undeserved favor and blessing), saw fit and was pleased [Isa. 49:1; Jer. 1:5.]
16 To reveal (unveil, disclose) His Son within me so that I might proclaim Him among the Gentiles (the non-Jewish world) as the glad tidings (Gospel), immediately I did not confer with flesh and blood [did not consult or counsel with any frail human being or communicate with anyone].
17 Nor did I [even] go up to Jerusalem to those who were apostles (special messengers of Christ) before I was, but I went away and retired into Arabia, and afterward I came back again to Damascus.
18 Then three years later, I did go up to Jerusalem to become [personally] acquainted with Cephas (Peter), and remained with him for fifteen days.
