The issue, is that muslim would say the same of Mohammad. And both need to resolve the issue of the Before Times. Are 4000 years of people just hellbound because it took God 4000 years (or 4500 years for Mo) to send down a savior? Some say there's some after-the-fact absolution going on, but that implies that, down the road, ANOTHER absolver could appear and post-hoc save those in the poor timing windows.

It's a bad system. Whether true or not. The random African looks at the Mormon OR Muslim missionary, who arrives a week after their parents die. Oh, the parents missed the window, they're in hell, if only they lived for 8 more days, they could have gone to heaven, too bad. Missed it by thaaaat much, eternity of torture, lol. It's simply a bad system.

And God wouldn't make such an obviously a bad system. Which means our interpretation of it, our mortal view, must be flawed in some way: Perhaps nonbelievers aren't "saved", they're meritorious in their own right. The teachings and scriptures help one become more meritorious, but they, in themselves, cannot be the keys to the kingdom. One of an infinite number of possibilities.

Because God isn't some FOMO cell phone gacha game. There is no "ah, missed it by thaaat much, should have logged in one day sooner, or did one more pull". God is Eternal, the concept of FOMO is irrelevant to Him, and should be as well to His flock. Likely. Infinite possibilities, but that isn't one of them.

But we can judge (and feel free to judge me in turn, 'lest ye be judged' only matters if there's fault in the judgement) that the religion that says "enslave, torture, and kill those who don't believe in the exact specific minutae of our Abrahamic Lord" are probably further from the truth, than those who say "an all-loving God would still love an atheist, as we are ALL God's children, not just some of us... Just some of us are a bit estranged".

Why wouldn't the non sinner go to Heaven?

Because not submitting to the Abrahamic god is the greatest sin of all.

Why wouldn't the non sinner go to Heaven?

Believing in Jesus is acknowledging this and accepting his gift

My biblical understanding is that you're saved by faith and not works, which is why the non-sinner doesn't go to heaven. You can be a "good person" your entire life, but even if you pray and attend church, if you don't truly have belief and faith in Jesus, you don't go to heaven. Meanwhile, someone can live a life of horrible sin similar to what's mentioned in the video, but if that person finds faith and seeks forgiveness on their deathbed, they get to go to heaven.

This was always my issue with Christianity, and why it doesn't look very different from a number of other religions from an outside perspective. If you don't actually believe in Jesus, nothing you do will save you. You can live an identical life to a community leader in your church, but if he believes and you don't, that's all that matters when it comes to salvation.
