Matthew 6:26, 33-34

Behold the birds of the heaven, that they sow not, neither do they reap, nor gather into barns; and your heavenly Father feedeth them. Are not ye of much more value than they?

But seek ye first his kingdom, and his righteousness; and all these things shall be added unto you. Be not therefore anxious for the morrow: for the morrow will be anxious for itself. Sufficient unto the day is the evil thereof.
