He knows

Your heavenly Father knows that you need all these things. (Matthew 6:32)

In Bristol, England, George Muller operated an orphanage for two thousand children. One evening, knowing they had no food for breakfast the next morning, Muller called his workers together and explained the situation. After two or three prayed, Muller said, "That is sufficient. Let us rise and praise God for prayer answered." The next morning they could not push open the great front door.... They went out the back door and around the building. Stacked up against the front door were boxes filled with food. One of the workers later remarked, "We know Who sent the baskets, but we do not know who brought them!"

God often sends His help by way of human hands.
