If you meant the "God" of Christianity ...
"God's" work comes with one of the greatest costs I can think of. It isn't "free", but yes people choose to follow out of volition. Dedicating their life & soul to an amalgamation of filth, that is the antithesis of the natural order of this planet.
All to be cast in the "boiling pot of souls", so to speak. The very hell proclaimed by the Bible is right past those "pearly gates", or whatever those losers call them.
