Here, the Lord Says This is Effective

“Father, my wife has been acting strangely lately, always saying that someone is calling her.”

“Here you go, the Lord says this works.”

"This is?"

“M1911 Divine Inscription, hold it like this, aim it at your wife, and then pull this trigger.”

...

Serious version:

The whispers of the ancient gods could not drown out the crisp sound of a bullet being chambered.

The roar of the demon god could not drown out the booming of the ship's cannons.

The roar of the evil god was far less pleasant than the sound of a laser cannon charging.

A mercenary, summoned by the Buddha of Fire and reborn in another world, is to be hired by the gods as a priest to bring a little firepower shock to those unclean things that have been lingering in the material world for so long!

Don't worry, here you go, the Lord said this works! (Draws gun/rocket launcher/sniper cannon/matrix cannon/space-based cannon)
