I'm afraid you're going to force me to quote CS Lewis here.
"Are the gods not just?"
"Oh no, child. What would become of us if they were?"
God never gives us what we deserve. If he did, we'd be dead already. The world often falls below justice, but God always goes beyond it. The God who died for his creation erases our sins, and forgets our transgressions. God's wrath has a limit, but his love and mercy are infinite.
None of this had made me less afraid of death, but maybe it will help somebody.
