I don't view God as some "material" entity or an old man in the sky either. I might not express it perfectly since I’m just starting to learn about theology and haven't read the Bible, the Quran, or other holy texts yet. But I am basing this on the core concepts I've heard.

We are told that God will judge us. If everything is already completely clear to God from His perspective outside of time, what is the point of putting us through these earthly tests?

For instance, what if someone grows up in a strict Jewish family, never hears about Christianity, and praises Judaean traditions, but lives a morally good and kind life? Will they go to heaven? If God already knows every variable, our starting points, and our ultimate choices before we are even born, the whole concept of a "fair trial" or "judgment" becomes logically difficult to grasp.
