2 Corinthians 12:12-15

12Truly the signs of an apostle were wrought among you in all patience, in signs, and wonders, and mighty deeds. 13For what is it in which ye were inferior to other churches, except that I myself was not burdensome to you? forgive me this wrong. 14Behold, the third time I am ready to come to you; and I will not be burdensome to you: for I seek not yours, but you: for the children ought not to lay up for the parents, but the parents for the children. 15And I will very gladly spend and be spent for you; though the more abundantly I love you, the less I am loved.1
