This woman had two choices. To do as he said or not to do it. She decided to listen to the man of God and because she did, God was true to His word and the oil and the meal lasted until the rain came again. Had the widow not trusted God to keep His word, her and her son would have surely died. God would have found another way to feed Elijah.
There may come a time in your life when you may have to share with someone from the little you have. Maybe you too may not know where your next meal is coming from. Don't be afraid to share, because the same God that Elijah trusted will also come through for you too. If there are difficulties in your life today and there seems to be no way out that you can see, remember, there is a God in Heaven that cares about you. He will meet your every need if you trust him and don't doubt. Take Him at His word. He will not fail you.
