8Then the word of the Lord came to him, saying, 9“Go now to Zarephath, which belongs to Sidon, and live there; for I have commanded a widow there to feed you.” 10So he set out and went to Zarephath. When he came to the gate of the town, a widow was there gathering sticks; he called to her and said, “Bring me a little water in a vessel, so that I may drink.” 11As she was going to bring it, he called to her and said, “Bring me a morsel of bread in your hand.” 12But she said, “As the Lord your God lives, I have nothing baked, only a handful of meal in a jar, and a little oil in a jug; I am now gathering a couple of sticks, so that I may go home and prepare it for myself and my son, that we may eat it, and die.” 13Elijah said to her, “Do not be afraid; go and do as you have said; but first make me a little cake of it and bring it to me, and afterwards make something for yourself and your son. 14For thus says the Lord the God of Israel: The jar of meal will not be emptied and the jug of oil will not fail until the day that the Lord sends rain on the earth.” 15She went and did as Elijah said, so that she as well as he and her household ate for many days. 16The jar of meal was not emptied, neither did the jug of oil fail, according to the word of the Lord that he spoke by Elijah. (1 Kings 17:8-16, NRSV)
The widow was ready to go and make the last meal for her and her son. She had no one to take care of them and only enough for a little meal for the 2 of them. But the Lord God told Elijah that a widow would provide for him.
And he believed God, and so did the widow. All three of them ate for many days on the meal and oil that would have given one meal.
What will God do for you if you believe?
