Excerpt from Dynamics for Living by Charles Fillmore:
“In the Old Testament the tithe or tenth is mentioned as a reasonable and just return to the Lord by way of acknowledging Him as the source of supply. Tithing is the giving of a tenth of one’s supply to God and His work. Tithing is a tacit agreement that man is in partnership with God in the conduct of his finances. This leads to confidence and
assurance that whatever is done will bring increase of some kind.
