“Teach us to number our days that we may get a heart of wisdom” (Psalm 90: 12) is one of my favourite verses in the Psalms.
In an excerpt from his new book, Learning To Love The Psalms, Robert Godfrey points out that the lesson of the verse is not to focus on making the best use of the number of days we get, but to be challenged by the shortness of the time we have here to look to eternity.
From the post.
If our need is to number our days by contrasting their shortness with the eternal nature of God, then our prayer to God is that He would teach us: “Teach us to number our days.” We will never learn that lesson in our own strength. We are not only ignorant if left to ourselves, but we suppress the truth in unrighteousness (Rom 1:18). We convince ourselves that we have a long time to live, and as long as we are healthy, we really believe that we will live forever in this body. We need a teacher, and the only teacher who can rescue us from ourselves is God.
