1 Corinthians 12:17-19

If the whole body were an eye, where [would be the sense of] hearing? If the whole body were an ear, where [would be the sense of] smell? But as it is, God has placed and arranged the limbs and organs in the body, each [particular one] of them, just as He wished and saw fit and with the best adaptation. But if [the whole] were all a single organ, where would the body be?
