This is a common question: "Do children who can't understand the gospel go to hell." To me, it sounds very consistent with God's character that he gives grace to those who are not capable of knowing the truth (like 1 year old babies and even the mentally challenged 40 year old "babies" who were growth stunted due to neglect from a corrupt Serbian Orphanage).
However, what I do have a question and quite severe thought on is this: I'm sure a lot of you have watched Common Filth's Tumblristas and video compilations of degeneracy. But recently, he did a video compilation which shows even children even as young as 6 behaving in the most shockingly immoral, degenerate and hedonistic ways, (probably due to Destructive and Liberal Atheist Parenting):
> 6 year old girl watching gay porn and swearing at mom
> 7 year old girl mocking preachers
> 8-11 year old boys whining about Homophobia and retarded SJW shit and taking gender change surgery and talking unbelievably filthy things.
How does God deal with children like this? Do you have an geuss or theory about it? Ultimately, God knows what's best and will do the correct Justice.
