The world of the generous gets larger and larger; the world of the stingy gets smaller and smaller.
One who blesses others is abundantly blessed; those who help others are helped.
Proverbs 11:24-25

God is generous and so he calls us to be as well.  What we do with what God has given us shows the world where our hearts are at and helps proclaim the gospel. We want to glorify God with every area of our lives, and that includes what we do with our finances.
