God descended from Heaven to teach why mankind was created, and has begun to help mankind live a joyous life.
There is causality. We reap what we sow.
There is reincarnation. Cause and effect may not be immediate.
We sweep evil (arrogance, greed, and self love) from our thoughts and behavior, even when our karma brings up suffering and inconvenience. This will by the law of causality, bring upon joy in the future.
Shared joy is true joy. We want others to experience our joy. We pray (Joyous Service) to help God bring others to our churches, so we teach them God’s truth of causality and our special prayer.
All mankind living a joyous life with everyone helping each other.
