“Every man according as he purposeth in his heart, so let him give; not grudgingly, or of necessity: for God loveth a cheerful giver. And God is able to make all grace abound toward you; that ye, always having all sufficiency in all things, may abound to every good work.” II Corinthians 9:7–8
 

Give with the expectation that God will faithfully supply whatever you need, so that you can abound in good works!
