Reputation. Paul is still speaking about his return to Jerusalem and discussion with the church leaders. Read Galatians 2:6-8.
But from those who were of high reputation (what they were makes no difference to me; God shows no partiality)-well, those who were of reputation contributed nothing to me. But on the contrary, seeing that I had been entrusted with the gospel to the uncircumcised, just as Peter had been to the circumcised (for He who effectually worked for Peter in his apostleship to the circumcised effectually worked for me also to the Gentiles),
Galatians 2:6-8 NASB
One of the points that Paul is making is that he is no better or worse than the other church leaders. They have a high reputation, but Paul wants people to know that just because of their reputation didn’t make a difference to the him regarding the gospel or his relationship with Jesus.
We’re have to be careful not to place too much value on the people we are in contact with. People are not as important as God and that is Paul’s point here. Even though these were church leaders, Paul was concerned about what God had to say, not just other people. Do we get overly concerned about the influence of people in our lives, or are we focused on God’s influence in our lives?
