I understand what you are saying, but comfort zones are an illusion. Moses wanted no part of the burning bush and going back to tell Pharaoh "Let my People go." Moses was actually arguing with Almighty God about this "who am I that I should go?" Saul wanted no part of the donkey talking to him on the road to Damascus. He was in his comfort zone killing and persecuting Christians. Ever heard of Dave Wilkerson (The Cross and the Switchblade)? He was a drug addict, gang member, who was also pretty comfortable and didn't want to hear anything else.
You get my point. The harder someone is fixed in their (perhaps) incorrect beliefs, all the more harder that they will believe in the new information, if someone can only get through to them. They will be more "on fire" with this information than the ones who sort of lackadaisically agree. How to tactfully attempt this on an individual basis is the key.
