18 But our bodies have many parts, and God has put each part just where he wants it. 19 How strange a body would be if it had only one part! 20 Yes, there are many parts, but only one body. 21 The eye can never say to the hand, “I don’t need you.” The head can’t say to the feet, “I don’t need you.” 22 In fact, some parts of the body that seem weakest and least important are actually the most necessary.
