2 Corinthians 11:6
“But though I be rude in speech, yet not in knowledge; but we have been throughly made manifest among you in all things.”
For if he that cometh preacheth another Jesus, whom we have not preached, or if ye receive another spirit, which ye have not received, or another gospel, which ye have not accepted, ye might well bear with him.
For I suppose I was not a whit behind the very chiefest apostles.
But though I be rude in speech, yet not in knowledge; but we have been throughly made manifest among you in all things.
Have I committed an offence in abasing myself that ye might be exalted, because I have preached to you the gospel of God freely?
I robbed other churches, taking wages of them, to do you service.
