The first reading of the day is about Elijah assuring the widow that she will have food and oil enough to last, if she would first serve him a morsel (the only food left) before she and her son has it. It is interesting to note the condition that Yahweh (through Elijah) puts for his generous offer of providing food in time of drought and famine.
The jar of flour shall not go empty, nor the jug of oil run dry, until the day when the Lord sends rain upon the earth.The "offer" is not for eternity, but till the time, the required resources are available for them to make their own food. God does not make us mere receptacles of His gifts but provides us with resources to make our own 'daily bread'. And in times when we do not have these resources at hand, He is willing to step in and provide the required goods, but again, not for ever, till the resources are available.
