Your faith can be tested by an obedience that does not make sense.  A single mother was preparing to eat her last meal with her son during a great famine.  She had her faith surprisingly challenged by a prophet who asked for water and a meal.  God draws her to this sacrificial hospitality.  God has committed the resources of heaven to those who totally trust and completely obey.  When He leans on you it is an invitation for you to lean on Him.

Then Elijah said to her, “Do not fear; go, do as you have said, but make me a little bread cake from it first and bring it out to me, and afterward you may make one for yourself and for your son.  For thus says the LORD God of Israel, ‘The bowl of flour shall not be exhausted, nor shall the jar of oil be empty, until the day that the LORD sends rain on the face of the earth.'”  I Kings 17:13-14
