My questions to them would be "if you had proof there was an all powerful, loving God, and he was the God of the Bible, would you accept Jesus and repent?" I agree, this is the place where many reprobates still reject God, but I'm not talking about them. I'm talking about people who DO accept and just want to see proof that he is the God of the Bible and not Quran or some other book. When you refuse to defend the very Bible you are preaching, that just makes your preaching weak and not nearly as effective as it could have been. The saved will be saved eventually, but if we don't help them out of sin, they will continue to contaminate the world and cause havoc with their sin.
