1 Corinthians 15 "The Dead will Rise"

I don't really know what to think of this chapter, it is all pretty much stuff I have heard before and stuff I agree with.  I do think Paul repeats himself a lot and as Paul is an excellent writer and he is inspired by God I can't help but wonder if the structural part of his writing(the repeating) means something.  My guess is that it is important.  This is very similar to repeats in Proverbs, such as how you should seek advice or those who trust in the Lord are better off.
