1 Corinthians 12:13-15

12:13 For in one Spirit we were all baptized into one body. Whether Jews or Greeks or slaves or free, we were all made to drink of the one Spirit. 12:14 For in fact the body is not a single member, but many. 12:15 If the foot says, “Since I am not a hand, I am not part of the body,” it does not lose its membership in the body because of that.
