They want to give!

God loves you. A lot.

He doesn't love you because He has to. He loves you because He wants to.

In that way, your donor team images God:

And you Philippians yourselves know that in the beginning of the gospel, when I left Macedonia, no church entered into partnership with me in giving and receiving, except you only. Even in Thessalonica you sent me help for my needs once and again. (Philippians 4:15-16 ESV)

Your donors want to give.

They don't do it because they have to. They do it because they want to.

Let that sink in...

They want to give.

They want to give to you.

So find them.  Let them.
