Galatians 2:1-2 NIV

[1] Then after fourteen years, I went up again to Jerusalem, this time with Barnabas. I took Titus along also. [2] I went in response to a revelation and, meeting privately with those esteemed as leaders, I presented to them the gospel that I preach among the Gentiles. I wanted to be sure I was not running and had not been running my race in vain.
