Certainly the body isn’t one part but many. If the foot says, “I’m not part of the body because I’m not a hand,” does that mean it’s not part of the body? If the ear says, “I’m not part of the body because I’m not an eye,” does that mean it’s not part of the body? If the whole body were an eye, what would happen to the hearing? And if the whole body were an ear, what would happen to the sense of smell? But as it is, God has placed each one of the parts in the body just like he wanted. If all were one and the same body part, what would happen to the body? But as it is, there are many parts but one body.
1 Corinthians 12:14-20 (CEB)
