Why do we speak as though we are an authority on things that we can really only have opinions about? It seems that there is a possibility that we may preach something other than the gospel and that it will stumble many who are being drawn into the kingdom.
I believe that it was Isaiah who said "How lovely on the mountains are the feet of them that bring good news"
Paul referred to the "good news of the gospel" and admonished us to preach "Christ and Him crucified" (I realize that I'm using a little king james here, but that's how I know these verses off the cuff.)
I believe that Paul taught that it was not up to us to preach the law any longer, but to preach grace, that Jesus wants to know us and that He wants to convict us of sin. He actually went out of His way to tell us to cover the sins of our brothers and sisters, and not seek legal counsel if at all possible, I would say to keep too many from knowing one another's dirty laundry as we tend to disqualify those who we know too much about from ministering to us.
Thus gossip is a heinous sin. It's always on the list when ever He makes one. And the first mention of real gossip was when Ham told his brothers of their fathers drunken nakedness.
I think that the gospel is that Jesus will go to any length to get us to choose Him, and that we being in Him need to work that out in ourselves and be encouraging to others that He has made a way... a narrow way because He is the "door", He is the way, the truth and the light/life. You don't do those things that will stumble someone else in their walk, and the rest is working out your own salvation.
