Galatians 2:2; 1 Thessalonians 3:5; Galatians 4:11

I went up because of a revelation and set before them (though privately before those lwho seemed influential) the gospel that mI proclaim among the Gentiles, nin order to make sure I was not running or had not orun in vain.

For this reason, iwhen I could bear it no longer, iI sent to learn about your faith, jfor fear that somehow kthe tempter had tempted you and lour labor would be in vain.

11 I am afraid sI may have labored over you in vain.
