1 Corinthians 4:12; 1 Corinthians 12:15; 1 Corinthians 12:21

12 And labour , working with our own hands: being reviled , we bless ; being persecuted , we suffer it :
15 If the foot shall say , Because I am not the hand, I am not of the body; is it therefore not of the body?
21 And the eye cannot say unto the hand, I have no need of thee: nor again the head to the feet, I have no need of you.
