I heard the Spirit of the Living God say, 
Purity in the offering. I desire clean hands and a pure heart. Let this be the way you give — joyfully with no strings attached Give with just an expectation of a good return, because Your Father in Heaven sees you, and He delights in a cheerful giver. He is the Rewarder of those who diligently seek Him. Giving is a part of seeking My Kingdom. Giving opens the door to the Kings’s heart.
