A drop in the bucket
Let's not refuse to give the little we have; God will multiply it. I remember an elderly man who was giving very little, but it was truly sacrificial. He had a younger friend who was always making fun of him. "Such need in the world, and yet you think that with your few dollars you will make a difference! Old friend, what you give is only a drop in the bucket." But the old man with rejoicing in his face turned to his friend and said, "Yes, all that God expects of me is my drop and He will see to the filling of the bucket."
