The word of the LORD came to him [Elijah], saying, "Go away from here and turn eastward, and hide yourself by the brook Cherith, which is east of the Jordan. "It shall be that you will drink of the brook, and I have commanded the ravens to provide for you there." So he went and did according to the word of the LORD, for he went and lived by the brook Cherith, which is east of the Jordan. The ravens brought him bread and meat in the morning and bread and meat in the evening, and he would drink from the brook.
It happened after a while that the brook dried up, because there was no rain in the land. Then the word of the LORD came to him, saying, "Arise, go to Zarephath, which belongs to Sidon, and stay there; behold, I have commanded a widow there to provide for you."
1 Kings 17:2-9
God provided for the needs of his obedient servant, but God did not provide through His disobedient people. That is the point that Jesus makes when He comments on these verses. There were many widows in Israel, but God used a Gentile widow to provide for His servant. There were lots of clean birds in Israel, but God chose an unclean bird to feed His servant. The Gentile people who did not know God were cleaner in their uncleanness, than God's own people in their careless disobedience.
God provides for His servants, but God provides in the way God chooses not the way the servant chooses. God may provide a drying brook for a few days of water, or an open unfailing faucet. He may humble us with thirst, or He may give abundance. But every provision of God, draws His servants closer to His heart!
The generous soul will be made fat [given plenty],
I know how to be brought low, and I know how to abound. In any and every circumstance, I have learned the secret of facing plenty and hunger, abundance and need. I can do all things through him who strengthens me. Yet it was kind of you to share my trouble.
For me to live is Christ.
