The Heart of God - Generosity

I recently read a book that a friend gave me to read that talked about living life the way God intended us to live it - blessed. The writer, Robert Morris, pointed out that there are 3 levels of generosity or of being a good steward that the Bible presents. The first, and the most I've ever really thought much about, is the tithe or the tenth. This is a principle laid out way back before the Jewish nation of the Old Testament even had the 'law'. Morris thinks that statistically most of those who claim to follow Jesus don't do this today. In Morris' opinion (and from a passage in Malachi 3), those who don't give God the top 10% are subjecting themselves to a curse. Ouch! For me, I give my 10, but, I have to admit that God has been dealing with me about the 90...it's still not MINE...its His and always will be - He's just loaned it to me. Morris digs deeper to talk about going above the 10% into the realm of both offerings AND extravagant gifts (like a year's salary or a car or house or something). In both of these 'above the 10' categories, he speaks of relying on God's Spirit to direct us. So, after reading this book, called "The Blessed Life", I realized that my attitude had to change regarding the 90, and, that I need to be walking close to the Lord and listening to Him on opportunities for me to be generous in the 'above the 10' category...Lord, help me obey You in this and help me be truly GENEROUS!
