Gratitude to God for His generosity to me is not real gratitude until I have been changed into a person of generosity.  One way of saying thanks for all the Father has given us is to give to others.  We who are on the receiving end of the Father’s generosity are called to give as liberally as we have received.  God always brings us face to face with enough needs to test our gratitude. 

“Give, and it will be given to you. They will pour into your lap a good measure—pressed down, shaken together, and running over. For by your standard of measure it will be measured to you in return.” Luke 6:38 (NASB)
