Christians are under the New Covenant. They are not under the Old Covenant. Tithing is an Old Covenant command, it is NOT a New Covenant ordinance. But there are a lot of seeker-driven (entertainment-driven) "churches" who have a lot of bills to pay in order to afford to keep their shows going. So they've reinstituted the Old Covenant tithe. But in order to "sell" the tithe these "churches" oftentimes have to employ the use of goofy entertainment to help ease the money out of the people's wallets.
Know the Truth
Christians are not obligated to tithe!
“Each one must give as he has decided in his heart, not reluctantly or under compulsion, for God loves a cheerful giver.” (2 Corinthians 9:7)
