1 Corinthians 12:17-20

17If the whole body were an eye, where would the sense of hearing be? If the whole body were an ear, where would the sense of smell be?

18But in fact, God has arranged the members of the body, every one of them, according to His design. 19If they were all one part, where would the body be? 20As it is, there are many parts, but one body.
