1 Corinthians 12:12-22

For just as the body is one and yet has many parts, and all the parts, though many, form [only] one body, so it is with Christ. For by one [Holy] Spirit we were all baptized into one body, [spiritually transformed—united together] whether Jews or Greeks (Gentiles), slaves or free, and we were all made to drink of one [Holy] Spirit [since the same Holy Spirit fills each life]. [Rom 3:22; Gal 3:28] For the [human] body does not consist of one part, but of many [limbs and organs]. If the foot says, “Because I am not a hand, I am not a part of the body,” is it not on the contrary still a part of the body? If the ear says, “Because I am not an eye, I am not a part of the body,” is it not on the contrary still a part of the body? If the whole body were an eye, where would the hearing be? If the whole [body] were an ear, where would the sense of smell be? But now [as things really are], God has placed and arranged the parts in the body, each one of them, just as He willed and saw fit [with the best balance of function]. If they all were a single organ, where would [the rest of] the body be? But now [as things really are] there are many parts [different limbs and organs], but a single body. The eye cannot say to the hand, “I have no need of you,” nor again the head to the feet, “I have no need of you.” But quite the contrary, the parts of the body that seem to be weaker are [absolutely] necessary
