Be careful for nothing. How to learn not to worry is one of the lessons everyone should master. Worry is a terribly wasteful experience. It uses up the strength we need for our duty. It unfits us for doing our work well. It is dishonoring to God, for He has promised to care for us, if only we do His will faithfully. Then it is utterly fruitless, for it does not take away the things it frets over. The Bible gives many lessons on the subject, but none that makes plainer just how we are to eliminate worrying from our life than what Paul here tells us to do. First of all, we are simply not to worry. “In nothing be anxious.” There is no room for exceptions, special circumstances, and all that. We are not to be anxious about anything. What then shall we do with the matters that we are disposed to worry over? Put them into the hands of God in prayer, and leave them there. If we do this the peace of God will guard our hearts, our thoughts, from all anxiety. It will be a great deal to us in every way to learn this lesson.
