18 As it is, we see that God has carefully placed each part of the body right where he wanted it. 19 But I also want you to think about how this keeps your significance from getting blown up into self-importance. For no matter how significant you are, it is only because of what you are a part of. An enormous eye or a gigantic hand wouldn't be a body, but a monster. 20 What we have is one body with many parts, each its proper size and in its proper place. No part is important on its own. 21 Can you imagine Eye telling Hand, "Get lost; I don't need you"? Or, Head telling Foot, "You're fired; your job has been phased out"? 22 As a matter of fact, in practice it works the other way - the "lower" the part, the more basic, and therefore necessary. You can live without an eye, for instance, but not without a stomach. 23 When it's a part of your own body you are concerned with, it makes no difference whether the part is visible or clothed, higher or lower. You give it dignity and honor just as it is, without comparisons. 24 If anything, you have more concern for the lower parts than the higher. If you had to choose, wouldn't you prefer good digestion to full-bodied hair? 25 The way God designed our bodies is a model for understanding our lives together as a church: every part dependent on every other part, the parts we mention and the parts we don't, 26 the parts we see and the parts we don't. If one part hurts, every other part is involved in the hurt, and in the healing. If one part flourishes, every other part enters into the exuberance.

Commentary on 1 Corinthians 12:12-26
(Read 1 Corinthians 12:12-26)
Christ and his church form one body, as Head and members. Christians become members of this body by baptism. The outward rite is of Divine institution; it is a sign of the new birth, and is called therefore the washing of regeneration, Titus 3:5. But it is by the Spirit, only by the renewing of the Holy Ghost, that we are made members of Christ's body. And by communion with Christ at the Lord's supper, we are strengthened, not by drinking the wine, but by drinking into one Spirit. Each member has its form, place, and use. The meanest makes a part of the body. There must be a distinction of members in the body. So Christ's members have different powers and different places. We should do the duties of our own place, and not murmur, or quarrel with others. All the members of the body are useful and necessary to each other. Nor is there a member of the body of Christ, but may and ought to be useful to fellow-members. As in the natural body of man, the members should be closely united by the strongest bonds of love; the good of the whole should be the object of all. All Christians are dependent one upon another; each is to expect and receive help from the rest. Let us then have more of the spirit of union in our religion.
