The sermon explored Psalm 71 and challenged us to aim to be people who grow old on the outside but are renewed with spiritual fervor on the inside. Drawing from examples like George Mueller and John Wesley, who experienced their most fruitful ministry seasons after age 70, we were reminded that spiritual vitality in old age doesn't happen by accident—it requires intentional decisions made throughout our lives. The key isn't to wait until we're 80 to implement Scripture, but to decide when we're 20, 35, and 47 how we'll spend our diminishing strength for God's glory. We also examined our responsibility to honor the aged among us, recognizing them as tested saints who have learned to trust Jesus over the long haul through many troubles and calamities.
