Amen to your last statement Aineo. And thanks for that verse, it's an excellent one.
All I can say about "interpretation" is that most positions argued here can never be "proven" as such, and so seem to end up being mindlessly debated without going anywhere. So I'm inclined to just trust God knows what he's doing and not to worry myself by bickering with people who aren't going to change their views just as much as I'm not going to change mine.
1 Corinthians 12 vs 4-6
There are different kinds of gifts, but the same Spirit. 5There are different kinds of service, but the same Lord. 6There are different kinds of working, but the same God works all of them in all men.
