Jesus asks a very simple, yet profound, question in Luke 12:25. Worrying about something completely out of your control is useless and, as the scripture implies, won't accomplish anything or "add a single hour to your life." So all we can do is let go of our worry and trust in God. As to many things in our life, we would be fools not to be concerned but,we must separate concern from worry. Not easy I admit, but necessary. Concern causes us to take action and hopefully, to pray. Worry does nothing to solve the situation and demonstrates our lack of faith in God. Concern vs worry. Think about it.
