"For thus saith the LORD God of Israel, The barrel of meal shall not waste, neither shall the cruse of oil fail, until the day that the LORD sendeth rain upon the earth. And she went and did according to the saying of Elijah: and she, and he, and her house, did eat many days. And the barrel of meal wasted not, neither did the cruse of oil fail, according to the word of the LORD, which he spake by Elijah."
During the great drought that came on Israel because of Ahab's idolatry, Elijah was sent to stay with a widow who was very poor. At a time when most people were struggling, she was literally down to making one last meal for herself and her son. She had reached the end of her rope. Yet when the prophet of a foreign God showed up at her door, she agreed to his request to feed him before her own son—trusting in the promise that he made on God's behalf. The little that she had lasted for the rest of the famine. God is always faithful.
There is no need we will ever face that will cause God to have to take out a loan or scramble for the resources to meet it. He owns everything, and He is able to do whatever is necessary to meet any challenge we may face. Those who trust in the Lord will never be disappointed or abandoned. David wrote, “I have been young, and now am old; yet have I not seen the righteous forsaken, nor his seed begging bread” (Psalm 37:25).
We are tempted to self-reliance and to determine what is possible by what we have. Yet God calls us to live on a different level, to live in faith in His abilities rather than our own. Whether we have a tiny bit or a large amount does not impact His ability or willingness to help in time of need.
Our lack of resources never impacts God's ability to provide for whatever we may need.
