The word ?tithe? literally means ?a tenth.? We return to the Lord 10% of what He?s given us, because it belongs to Him. In Malachi 3:10-11, God says, ?Bring the whole tithe into the storehouse that there may be food in my house.? The storehouse is the Old Testament picture of the New Testament church. So as New Testament believers, we worship the Lord with the tithe: or ten percent. But giving away 10% of your income can be a big and often frightening commitment! That?s why we are offering?the 90 Day Tithe Challenge: a money back guarantee of sorts. Essentially, it?s a contract based on the promises of God in Malachi 3:10-11. We commit to you that if you tithe for three months or 90 days and God doesn?t hold true to His promises of blessing, we will refund 100% of your tithe. No questions asked.
