First, if we believe that God is Omnipotent, Omniscient and Omnipresent as I was taught in the last half of the last century, then He can do what He wants to do, and its none of our control or speculation that will alter that one bit. God does not even have to obey the Bible to get stuff done if you agree with the first part of that sentence. It would be TOO MANY contradictions in that idea.
I am sure that big changes need to be made, and there is plenty of old rotten junk out there that is not worth saving in any sense of the word. I believe in a Creator that can do some fantastic makeovers if we play by His non-rules that make him the boss. Instead we are listening to people who claim to be God's voice, but who cannot hear it themselves. Too many "false prophets" are cluttering up the landscape and are the real stumbling blocks for those who will lift their Cross and get hiking.
