Sometimes we are the source of God’s supply to others. Consider the great work of Samaritan’s Purse, Food For The Hungry, Salvation Army, and others.
A pious father always closed grace for the evening meal with these words: "Come, Lord Jesus, be our guest and bless what thou hast provided." "Papa," said the little son, "every evening you ask Jesus to come and be our guest, but he never comes." "My son," replied the father, "we can only wait. But we know that he will not despise our invitation."
"Well, then," asked the little fellow, "if we expect him to come and have dinner with us, why don’t we set a place for him at the table?" And so to save further embarrassing questions, the father permitted the boy to set a place at the table. Just then a knock came at the door. When they opened it a poor helpless waif stood shivering in the cold. The son thought for a moment and finally said, "I guess Jesus couldn’t come today, and so he sent this poor boy in his place." With little further conversation the little beggar boy was brought in and set at the empty place at the dinner table.
