But the manifestation of the Spirit is given to each one for the profit of all
This is a great passage that kind of summarizes the whole chapter. I strongly suggest reading the whole thing, but in accordance with my self-imposed short post requirement I only posted the one verse since I think it expresses the heart of the chapter: God wants to use us all for the benefit of us all! When we are all used by the Spirit the body will function properly and benefit us all. God has manifest His Spirit in all of us and all of us need to exercise our gifts in accordance to that. If he only wanted a few to exercise their gifts he would have only manifested his Spirit in a few, but he didn’t and so we all need to participate in the life of the church!
