For by the grace given to me I tell everyone among you not to think more highly of himself than he ought to think, but to think sensibly, in accordance with the measure of faith that God has distributed to each one of you.
For we do not dare to classify or compare ourselves with some who commend themselves. When they measure themselves with one another and compare themselves to one another, they do not show good sense.
Are you looking only at outward appearances? If anyone is confident that he belongs to Christ, he should remind himself that just as he belongs to Christ, so we also belong to Christ.
For if someone comes to you and preaches a different message about Jesus than the one we preached, or if you receive a different spirit than the one you received, or a different gospel than the one you accepted, you bear with it well enough.
We are from God. Whoever knows God listens to us; whoever is not from God does not listen to us. By this we know the Spirit of truth and the spirit of error.
