ELI5: Explain Like I'm 5

Known unto God

"Known unto God" is a phrase that you might see on memorials or graves of soldiers who have died in wars. It means that even though we might not know the exact names of every soldier who has died, or even where their body is, they are still known and remembered by God.

Think of it like this: Imagine you and your friends are playing a game and one of your friends has to leave before the game is over. Even though they're not there with you anymore, you still remember them and think about them. So, even though we can't see or talk to the soldiers who have died, we still remember them in our own way, and God remembers them too.
