Go ahead and keep what belongs to God. Will a man rob God? Yes. Some will. Render to God that which is God's.
Do you realize how childish and spiritually immature you sound? Claiming over and over that something is biblical does not make it so. Is this how you pastor, prepare your sermons?
Does the pastor have Gods' PO BOX or something, to forward the money to Him?
Or, if the buck stops at the pastor, is he our official, representative for Christ?
I'm glad I will not have to stand before God and explain to him how I ever embraced such a silly doctrine as this. God help the sheep these men pastor.
