1 Corinthians 9:26

So also you, unless you utter by the tongue a word that is clear, how will it be known what is spoken? For you will be speaking into the air.

And I went up because of a revelation, and I laid out to them the gospel which I preach among the Gentiles, but I did so in private to those who were of reputation, lest somehow I might be running, or had run, in vain.

not because we do not have the authority, but in order to offer ourselves as a model for you, so that you would imitate us.

Fight the good fight of faith. Take hold of the eternal life to which you were called, and you made the good confession in the presence of many witnesses.

I have fought the good fight, I have finished the course, I have kept the faith.
