Oh, I'm glad you said that, Bo, because, that's the way I believe. I don't think people should be tithing simply because it was an Old Testament Law. If we are tithing at all, it should be out of a grateful heart and not out of duty. God only wants our best.
I actually think it would be best not to tithe at all, but to bring our grateful gifts to the storehouse (churches) from what God has blessed us with. But, now the churches expect it, and they have grown accustomed to it and would probably go broke if people stopped tithing.
I don't believe God intended there to be mega churches, where so much money is spent on lighting and speakers, etc. I think churches were supposed to be small enough to include every individual and we were supposed to be like a family who communed together and worshipped God together, but don't get me started.
