Contradiction of Theism: Worship vs. Helping Others
I think there is a crucial logical contradiction of ALL world religions (beyond just Christianity).
1. IF God exists and is omni-benevolent (all-good), he posits the golden rule: treat others as you would be treated. Or even better: prevent the suffering of others. If I had no food, shelter, security, etc., I would want others to help me out, hence, I would want others to prevent me from suffering.
2. God asks us to be selfless. Wouldn't God then be selfless too? Was Jesus an example of a selfless being?
3. If God is selfless and wants us to prevent our fellow humans from suffering, then WHY WOULD HE WANT US TO WASTE TIME WORSHIPING HIM?
4. Finally, if God requires worship, that would mean that he needs something. If he needs something; anything at all; if he desires ANYTHING; then he ceases to be God as defined by all religious traditions. God cannot need anything. There is no way to "glorify" a being that is already maximally glorified by his very nature. There's no way to add a finite number to infinity and make it "more" than infinity.
Thus, there is no point to worship God if he exists, because God would not want us to worship him. Spend your time helping people on Earth that have real needs; because God needs nothing, not even your "glorification" through worship. He's already maximally "glorious" by definition.
Go do community service on Sundays. Don't pray and worship an imaginary being who wouldn't want you to worship him IF he existed.
