And this is exactly why Jesus said, "Take therefore no thought for the morrow: for the morrow shall take thought for the things of itself.

Instead of worrying about and preparing for what to do in a wheat shortage crisis, true Christians were focused properly on the activity of what we have been commissioned to do.
