He says they began with Spong, I'm inclined to think they began earlier and Spong was just a symptom. But he is absolutely correct when he says the current heresy began as little tiny compromises with the World.
As C.S. Lewis said (putting words in the mouth of Screwtape), "Indeed the safest road to Hell is the gradual one – the gentle slope, soft underfoot, without sudden turnings, without milestones, without signposts."
And who was it that said, Satan’s greatest lie is that he does not exist.
I am always amazed and a little amused at these folks who think they know better than God.
GOD BLESS THOSE WHO PRAY
