For by the grace given to me, I tell everyone among you not to think of himself more highly than he should think. Instead, think sensibly, as God has distributed a measure of faith to each one. Now as we have many parts in one body, and all the parts do not have the same function, in the same way we who are many are one body in Christ and individually members of one another. According to the grace given to us, we have different gifts:
If you are a hand, and you feed a mouth, the stomach will distribute the benefit to the whole body, including yourself. Seemingly unrelated benefits will be experienced when we are all doing our parts. I will bless members of the Body I never encounter directly when I do my part.
When we build each other up, especially when we do it directly, we all become capable of accomplishments that we could never do apart from the rest of the Body doing their parts.
