An orca whale, who researchers have named “Granny,” apparently knew the importance of her role in the life of her “grandbaby whale.” The young whale’s mother had recently died, and the orphaned whale was not yet old enough to thrive without protection and support. Granny, though in her eighties (or older), came alongside to teach him what he needed to know to survive. Granny corralled some fish for the younger whale instead of consuming them herself, so he would not only have a meal but would also learn what to eat and where to find the salmon he’d need to live.

We too have the distinct honor and joy of passing on what we know—we can share about the wonderful works and character of God with those coming after us. The aging psalmist asks God to allow him to “declare [His] power to the next generation” (Psalm 71:18). He earnestly wishes to share with others what he knows of God—His “righteous deeds” and “saving acts”—that we need to flourish (v. 15).

Even if we don’t have the gray hairs of old age (v. 18), declaring how we’ve experienced the love and faithfulness of God can benefit someone on their journey with Him. Our willingness to share that wisdom might just be what that person needs to live and thrive in Christ even in adversity (v. 20).
