Mixing up the Gospel?

Big Doofus posted a very thoughtful comment on the worship music post which I think is at the crux of a huge doctrinal tension. I thought it deserved a whole new thread of its own. It read, in part:

"I really think that our corporate worship should reflect united praise to God for who He is, what He has done, and what He will do...I just don't want to mix up the real gospel with the results of the gospel in our lives--if that makes any sense."

The whole reason we discuss things here is to make unified sense of differing views. We Caffecclesiologians obviously are looking at this differently, so let's tackle it. DOES it make any sense?

What IS the gospel? What IS its result in our lives? What truth is at stake if the two are mixed? Or, what is at stake if we fail to mix them?

Does Christ Jesus separate the gospel from the results of the gospel in our lives? Or are they actually one thing in Him.

What did Jesus say?
What did the apostles say?
What did the prophets promise?

(I think I scheduled this to post on Monday AM. I don't want to cut of the great discussion on the last post.)
