Heaven, increases all feelings to their extreme quality. Hell, decreases all feelings to their minimum quality. So if someone dies feeling sorrow, rage, hate and goes to heaven they’re going to feel all those to their extreme, that is why god creating hell is actually an act of love because he wants us to feel sorrow, hate, rage as little as possible and feel love to its extreme.
A lot of people today can barely learn one language. You’re suggesting that an entire religion’s followers learn Ancient Greek, Hebrew, and Aramaic, all 3 in dialects that are 2000 years old at the latest. I’m pretty sure God will accept whatever language people happen to read the Bible in.
That said, you do get so much more depth out of the Bible when you look at the original language. From Eve being made from Adam’s side, not just a rib, to King James hiding that God will protect you from the tyrant. I’d love to dive into the original language more, but I’m far from a linguist.
