Galatians 2 - Living by faith

Galatians 2

Paul continuous to lay out his case for his preaching to the gentiles and was moved by God in a “revelation” to go to Jerusalem. He needed to receive confirmation from the elders in Jerusalem that as far as the preaching of the gospel that everyone was on the same page. Man is never justified by the works of the Law but through faith this Christ Jesus alone.

Paul’s testimony and ours should be, Galatians 2:20 (NASB) 

I have been crucified with Christ; and it is no longer I who live, but Christ lives in me; and the life which I now live in the flesh I live by faith in the Son of God, who loved me and gave Himself up for me.
