Era of Divine Grace

In a world where gods use faith as currency and humans use divine grace as a ladder, history itself is the biggest lie. The twelve main gods came in the name of "salvation" and divided the world into three continents and nine levels. The prayers of believers build the kingdom of God, and the devout kneeling strengthens the throne. Gods and demons are fighting on the Holy Relic Island, and the erased truth is buried deep in the ruins. When the corruption of demons was identified as original sin, no one realized that it was just the reverberation overflowing from the gods absorbing faith. Who is closer to the essence of the world, those children who "fail" in the listening ceremony or the believers who climb the ladder of divine grace? This is a scam that has been going on for millions of years. When the last piece of faith is harvested, will humans become gods, or will gods eventually fall?
