2 Corinthians 12:12-14

Truly the signs of an apostle were wrought among you in all patience, in signs, and wonders, and mighty deeds. For what is it wherein ye were inferior to other churches, except it be that I myself was not burdensome to you? forgive me this wrong. Behold, the third time I am ready to come to you; and I will not be burdensome to you: for I seek not your's, but you: for the children ought not to lay up for the parents, but the parents for the children.
