Charles Spurgeon Commentary Matthew 6:30-33

"But if God doth so clothe the grass of the field, which to-day is, and to-morrow is cast into the oven, [shall he] not much more [clothe] you, O ye of little faith? Be not therefore anxious, saying, What shall we eat? or, What shall we drink? or, Wherewithal shall we be clothed? For after all these things do the Gentiles seek; for your heavenly Father knoweth that ye have need of all these things. But seek ye first his kingdom, and his righteousness; and all these things shall be added unto you." — Matthew 6:30-33 (ASV)

If you want string and brown paper, you do not need to go into a shop to buy them; if you buy certain articles, you get string and brown paper in the bargain. So, when you go to God, seeking first his kingdom and his righteousness, these other things, which are merely the packing, as it were—the string and the brown paper—are given to you in the bargain. He who gives you the golden treasures of heaven will not allow you to lack the copper treasures of earth.
