Reaction - The Wrathful God of the Old Testament

For the original quiz:

[kris_is_in_the_air]

I seek understanding. Does the bible speak how God judges deceased children and infants? To what lengths will god be merciful to ignorant children whom never had the opportunity to accept or reject christ?
Also, "the real mystery of life is not hell, its heaven" 3:58 surprised me, interesting to think about.
