Sorry if I misunderstood you - which often happens as we respond to a post of only a few words which don't reveal the whole person.
I don't like to judge whether any will get to Heaven or not, as I don't have the ability to know their total being - heart and soul - like God does. And, we are not here to judge but to live our lives as best we can.
The bible-thumping you call me on merely comes as a response in defense of Jesus, God, the search for the truth God gave us rather than the distortions man has created in order to adjust God's words more to man's liking.
There is nothing wrong with that. I do the very same for President Bush, this country and the conservative views. So, if it appears I am jumping on a point of criticism, it is probably due to my training on FR as we respond to discussion points - often with great fervor.
As far as children and the hereafter - "let not your heart be troubled" (as Sean would say). Children are not of the age of accountability to understand and know what decisions of life are to be made. So, of course, they are welcomed into Heaven. In fact, we are told that our hearts must be as the hearts of children to please God (or something along that line).
I am in agreement with you on wondering how people can NOT believe in God. As you said, there is so much history and teaching. How did one man - Jesus- manage to make such a difference to so many people? I guess non believers never ask themselves these questions, so , it is good that you try to make them think about it.
