1 Corinthians 12:14-21

For the body is not one member, but many. If the foot shall say, Because I am not the hand, I am not of the body; it is not therefore not of the body. And if the ear shall say, Because I am not the eye, I am not of the body; it is not therefore not of the body. If the whole body were an eye, where were the hearing? If the whole were hearing, where were the smelling? But now hath God set the members each one of them in the body, even as it pleased him. And if they were all one member, where were the body? But now they are many members, but one body. And the eye cannot say to the hand, I have no need of thee: or again the head to the feet, I have no need of you.
