But David’s vision is more comprehensive than mere protection. He wants so to live in old age that he passes on his witness to the next generation. His aim is not to live comfortably in retirement, but to use his senior years “to declare your power to the next generation, your might to all who are to come.” That is a prayer eminently worth praying. Should not senior saints be praying for grace to pass on what they have learned to a new generation? Perhaps this will be one on one, or in small groups. Perhaps one of them will take under his or her wing some young Christian or abandoned waif. Perhaps some experienced prayer warrior will teach a young Christian leader how to pray. And when there is too little strength even for these things, we shall pray that God’s grace will so operate in our weakness that God will be glorified in us: perhaps we shall teach younger Christians how to persevere under suffering, how to trust in the midst of pain, and how to die in the grace of God.
