Taking a good look at our checkbook will tell us where our priorities are.
Absolutely. And any pastor who feels the need to threaten, strongarm or guilt-trip people about giving from the pulpit is leading a church that has not been taught proper biblical financial principles -- which is HIS fault!
If the issue is giving in general, then the matter is a simple one. We are to give because God is a giver. He owns the cattle on a thousand hills, and He owns the hills as well. John 3:16 states, "For God so loved the world that he GAVE..." The reason to give is not to overcome guilt for not giving, or to check off some line item on our spiritual checklist. It makes us more like our Father, like a kid who watches his dad shave and then mimics what he sees because he wants to be like Daddy. God is the Giver of all Good Things, and giving helps me conform to the Image in which I was created.
If it boils down to whether or not to give a literal tithe (tenth), well, there is Biblical precedent for that. We see the word in both the OT and the NT. What is more, the first recorded case of a tithe/tenth is in Genesis 14, where Abraham gives a tenth of his wealth to Melchizadek (sp?) after he bails Lot out of trouble. Melchizadek is typically held up as a type of Christ, so we see an OT picture of one way we should be worshipping the Lord. Giving IS worship.
Many inside and outside the church criticize tithes and offerings, because they feel like if God's so big then why does He need our money? As Bono said on U2's "Rattle And Hum" album, "And I can't tell the difference between ABC News, Hill Street Blues, and a man on the Old Time Gospel Hour taking money from the sick and the old. Well, the God I believe in isn't short of cash, mister." Well of course He's not, Bono. But that's because He already owns it all anyway. There's nothing that we have that wasn't given to us by God. If He owns it and has just entrusted portions of His holdings to us to manage for Him, then who are we to argue when He tells us what to do with it?
