Tithing should absolutely be taught but churches have to remain blameless.
-
Lay ministers. No paycheck.
-
Private method of tithing. No passing the plate around for shame.
The wilderness tent temple was commanded to be funded by voluntary tithing, before the advent of kings and taxes. God doesn't want your money per se but he wants you to sacrifice something of worth.
"Bring the whole tithe into the storehouse, that there may be food in my house. Test me in this," says the LORD Almighty, "and see if I will not throw open the floodgates of heaven and pour out so much blessing that there will not be room enough to store it."
Malachi 3:10
Jesus answered, "If you want to be perfect, go, sell your possessions and give to the poor, and you will have treasure in heaven. Then come, follow me."
Matthew 19:21
Stop being cheap with God. If you can't part with worldly junk and Jewish toilet paper, He knows your heart isn't ready.
