Giving is one of the most important spiritual practices we can develop. When we make a gift we bestow a since of value on the receiver, we recognize something of value within our own lives, and when times are lean, making a gift can be one of the only ways to free us from the fear of not having enough. It's simple math, if I have something that I can give away, be that 10 minutes of help or two dollars to share, that means I have been blessed with more than I need.
Ascribe the the Lord the honor due his name. Bring offerings and come into his courts. - From Psalm 96, verse 8
