1 Corinthians 12:12, 25-27

A person’s body is one thing, but it has many parts. Though there are many parts to a body, all those parts make only one body. Christ is like that also.

so our body would not be divided. God wanted the different parts to care the same for each other. If one part of the body suffers, all the other parts suffer with it. Or if one part of our body is honored, all the other parts share its honor. Together you are the body of Christ, and each one of you is a part of that body.
