For Those Who Follow By Warren Wiersbe
As we get older, things change. We must drop some things, and we must start others. Not much goes on continually--except in Psalm 71. David uses the word continually three times. First, he tells us that we can continually resort to the Lord in prayer: "Be my strong refuge, to which I may resort continually" (v. 3). No matter how old we get, we can pray, because the Lord never fails. We also can have continual praise. "My praise shall be continually of You" (v. 6). If prayer is without ceasing, then praise will be without ceasing. David also tells us, "I will hope continually" (v. 14).
"Now also when I am old and grayheaded, O God, do not forsake me, until I declare Your strength to this generation, Your power to everyone who is to come" (v. 18). Notice that David's focus is not simply on his needs. He wants to have his needs met so he can share the Lord with others. "You shall increase my greatness and comfort me on every side.... I will praise You" (vv. 21,22).
If we are resorting to the Lord continually in prayer, if we are rejoicing in Him continually in praise, if we are hoping in Him continually and laying hold of His promises, if we are saying that the best is yet to come and praise Him more and more, then we can grow old and grayheaded without fear. We'll be able to glorify the Lord, and we'll be able to share Him with others in the next generation. What kind of heritage are you leaving for future generations? What are you teaching them by word and example about God's strength and power? Will others put their faith in the Lord on the basis of your life and testimony?
You can always live to bring glory to God no matter what your age is. Those of us who are older can do that in a special way; we can teach the younger generation about His faithfulness. Preserve your Christian heritage for future generations. Let your life be a continual testimony for God.
