2 Corinthians 11:3-7

But I am afraid that, as the serpent deceived Eve by his trickery, your minds will be led astray from sincere and pure devotion to Christ.

For if one comes and preaches another Jesus whom we have not preached, or you receive a different spirit which you have not received, or a different gospel which you have not accepted, this you tolerate very well!

For I consider myself not in the least inferior to the most eminent apostles.

But even if I am unskilled in speech, yet I am not so in knowledge; in fact, in every way we have made this evident to you in all things.

Or did I commit a sin by humbling myself so that you might be exalted, because I preached the gospel of God to you without charge?
