We don't ask ourselves what it's about, and we tend to use it for our own purposes. For example, Psalm 23 is not about courage . I spend a great deal of my time as a minister, talking with people who are afraid, with people who are scared. They might be sick, or they might be threatened. All of us are scared at times.
Fear is a universal experience.
I will face what is coming. I will not run away from it. I will take my stand, and I will not let myself by moved. The 23rd Psalm is not about courage. Courage is the attitude, or the response, or the virtue, which is usually connected with soldiers.
