Yeah but his magic only works if you believe in him, so really it was for glory (lol)

One of the most famous stories in the Bible includes God magically killing the first born son of every family of non believers

He really did have a whole thing about killing sons lol

Listen, Old Testament God was still working out His whole "Canaanite storm deity" thing He had going on, it wasn't a good time.

That would be Jesus. For some reason, he was keen on the "execute rebellious children" thing and objected to carveouts that made it harder to implement.

That one isn't really about "non-believers"... Like, you can absolutely argue it was disproportionate and targeted kids for the sins of their parents, but come on
