This portion of scripture has really encouraged me over the years when money has been exceptionally tight:
Luke 12:22-40 And He said to His disciples, “For this reason I say to you, do not worry about your life, as to what you will eat; nor for your body, as to what you will put on. For life is more than food, and the body more than clothing. Consider the ravens, for they neither sow nor reap; they have no storeroom nor barn, and yet God feeds them; how much more valuable you are than the birds!
And which of you by worrying can add a single hour to his life’s span? If then you cannot do even a very little thing, why do you worry about other matters? Consider the lilies, how they grow: they neither toil nor spin; but I tell you, not even Solomon in all his glory clothed himself like one of these. But if God so clothes the grass in the field, which is alive today and tomorrow is thrown into the furnace, how much more will He clothe you? You men of little faith!
And do not seek what you will eat and what you will drink, and do not keep worrying. For all these things the nations of the world eagerly seek; but your Father knows that you need these things. But seek His kingdom, and these things will be added to you.
Do not be afraid, little flock, for your Father has chosen gladly to give you the kingdom. Sell your possessions and give to charity; make yourselves money belts which do not wear out, an unfailing treasure in heaven, where no thief comes near nor moth destroys. For where your treasure is, there your heart will be also. Be dressed in readiness, and keep your lamps lit.
Be like men who are waiting for their master when he returns from the wedding feast, so that they may immediately open the door to him when he comes and knocks. Blessed are those slaves whom the master will find on the alert when he comes; truly I say to you, that he will gird himself to serve, and have them recline at the table, and will come up and wait on them. Whether he comes in the second watch, or even in the third, and finds them so, blessed are those slaves. But be sure of this, that if the head of the house had known at what hour the thief was coming, he would not have allowed his house to be broken into. You too, be ready; for the Son of Man is coming at an hour that you do not expect.”
