Your hell question is, I think, among the best I've ever received.
Well, high praise indeed, I suppose, from McLaren. What, we may right ask, was this highly-praised query?
Why do you think all of those who vehemently defend eternal concious torment in the afterlife for the vast majority of humanity never live like they believe it. It seems to me that if they really believed it, they would never have kids (to spare them the large chance that they would experience ECT) and that they would spend every moment of their life screaming and frantically running around trying to rescue people. I've heard of these logically consistent people, but have never met one. Why do you think this is?
That's it? That's the question McLaren things is so good?
So, let's see--if you believe in Hell, and that it's eternal, you shouldn't have children? And you should go about like a maniac all the time, trying to rescue people?
First, upon what basis are Christians who believe in eternal punishment in Hell suppose to not have children? Upon the basis of fear? That's logical? No, this is asinine, silly, pathetic.
Children are a gift from God. Children are a blessing. They are also a responsibility. They will not raise themselves, but godly parents are to raise them to respect and love and fear God. Yes, even the aspect of their eternal destiny is a responsibility, and they are the ones who have a great say in that themselves, but Christians are commanded to live in faith in God, and not to cave in to fear and the nonsense behind this person's question.
Much the same could be said about the second part. There are many Christians who have gone to places where the Gospel has been little known or not known at all, and have presented the Gospel to those people.
But running around like a chicken with its head cut off will not work. There is a point at which we have done out duty, the Gospel has been presented, and after that, it's time to stop playing umpteen-zillion chorus during the altar call, to stop trying to manipulate. We may pray that they will respond differently later on, that perhaps God will grant them repentence, even an apostate like McLaren. But antics and theatrics on our parts will do no good.
So, I find McLaren's 'best' question to be little more than rubbish.
