15 But when it was the good pleasure of God, who separated me, [even] from my mother's womb, and called me through his grace, 16 to reveal his Son in me, that I might preach him among the Gentiles; straightway I conferred not with flesh and blood: 17 neither went I up to Jerusalem to them that were apostles before me: but I went away into Arabia; and again I returned unto Damascus. 18 Then after three years I went up to Jerusalem to visit Cephas, and tarried with him fifteen days. 19 But other of the apostles saw I none, save James the Lord's brother. 20 Now touching the things which I write unto you, behold, before God, I lie not. 21 Then I came unto the regions of Syria and Cilicia. 22 And I was still unknown by face unto the churches of Judaea which were in Christ: 23 but they only heard say, He that once persecuted us now preacheth the faith of which he once made havoc; 24 and they glorified God in me.

Commentary on Galatians 1:15-24

(Read Galatians 1:15-24)

St. Paul was wonderfully brought to the knowledge and faith of Christ. All who are savingly converted, are called by the grace of God; their conversion is wrought by his power and grace working in them. It will but little avail us to have Christ revealed to us, if he is not also revealed in us. He instantly prepared to obey, without hesitating as to his worldly interest, credit, ease, or life itself. And what matter of thanksgiving and joy is it to the churches of Christ, when they hear of such instances to the praise of the glory of his grace, whether they have ever seen them or not! They glorify God for his power and mercy in saving such persons, and for all the service to his people and cause that is done, and may be further expected from them.
