How about the preachers taking the podium for travel expenses only?
How about a 5 minute offering and speech instead of the 2 hour affair they insist on having that drive the masses from their seats even if they were there in the first place.
Have a development drive where for every $100 people spend on new clothing for GC, they send in $20 to support GC.
Raise ministerial dues.
Open the business sessions for video and teleconference, and have those ministers who would otherwise have spent money to attend send it into the general fund.
Scratch theatric lighting from the budget.
Put time limitations on sermons, offerings (above), speeches, special interests in order to save utilities.
I could go on but why...
