For this reason, when I could bear it no longer, I sent to find out about your faith; I was afraid that somehow the tempter had tempted you and that our labor had been in vain.
I went up in response to a revelation. Then I laid before them (though only in a private meeting with the acknowledged leaders) the gospel that I proclaim among the gentiles, in order to make sure that I was not running, or had not run, in vain.
Therefore, my beloved brothers and sisters, be steadfast, immovable, always excelling in the work of the Lord because you know that in the Lord your labor is not in vain.
