If worship has a place for us all (ch 12) and love gives us a good map for how (13), chapter 14 tells us that worship is best done in an orderly manner. We do it together in love in away that gives God glory. He brings order to chaos, so too our worship should be orderly and not chaotic.
Apparently the people of Corinth were doing some crazy things and Paul sets them straight! I wonder what would be said about ours today?
