Luke 12:28-31

But if this is how God clothes the grass which is in the field today and tomorrow is thrown into the furnace, how much more will He clothe you? You of little faith! So as for you, do not seek what you will eat and what you will drink; nor have an anxious and unsettled mind. For all the [pagan] nations of the world greedily seek these things; and your [heavenly] Father [already] knows that you need them. But [strive for and actively] seek His kingdom, and these things will be given to you as well.
