I just don't get it.
A guy like Hitler who started WW2 and almost wiped out the Jews could go to Heaven if he just admitted his sins and found God before he died.
Yet, a school teacher who devoted her life to the betterment of society by educating the young could find herself in Hell if she never committed herself to God before her death.
Hitler- Heaven
Teacher who did everything morally right- Hell
Seems about right.
If you are genuinely seeking an honest response, then I will give it a shot.
We've been taught in some capacity or another that Adam and Eve were kicked out of the Garden of Eden because they made a mistake and sinned. This has lead many to grow up thinking that their value and their worthiness of being loved and/or saved is based on how well they perform. That couldn't be further from the truth. The reality, and you can go to Genesis 3 and read for yourself, is that Adam and Eve were kicked out of the garden because they didn't take ownership of their sins. Eve blamed the serpent. Adam blamed Eve. God looked at them both and was like, "I know where this is going..." So when we repent of our sins, it's not bowing down like a slave and declaring that God is your master. God doesn't want slaves, and he doesn't want us living with a slave mindset. In fact, God wants us to live like royalty. Repentance is a choice. It's saying, "I'm going to take ownership of myself align myself with not only who God is, but who He created me to be." That's when relationship with God is established, and since God is a good and loving God who wants us to be the absolute very best that we were created for, it makes for a pretty wild and amazing ride.
So going back to your original question of why Hitler would go to heaven and the school teacher would go to hell, we need to look at it from a different angle. Leave the performance side out of it. In your scenario, Hitler lived his life and turned back to God near his end. The school teacher rejected God their whole life, and may have not. If we live our whole lives thinking that our actions could never possibly be forgiven, then we don't know God. And additionally, if we live our whole lives thinking we're unworthy of being loved, then we're believing a lie.
You are worthy. You are loved. You are made good. You are made for great things.
