The old lighthouse may be crumbling, but it continues to beam guiding light across the stormy sea. The Hooper Island Lighthouse in Chesapeake Bay has been steering seafarers since 1901, but many people think it’s time for the old beacon to retire to the junkyard. What used to be a brilliantly towering cylinder of hope is now a worn out and rusty hunk of metal. However, according to the Washington Post, the lighthouse isn’t going anywhere since it remains as an “active aid to navigation for the U.S. Coast Guard.” Even though it is old and frail, it still has a pivotal purpose: lighting the way.

Similarly, all Christians are called to be a “lighthouse” for sinners sailing in the darkness of depravity. The “children of light” are commanded to radiate the light of the glory of Christ in order to direct wayward sinners to the “Father of lights” (cf. 1 Thess. 5:5; James 1:17). As Jesus said, “Ye are the light of the world. A city that is set on an hill cannot be hid. Neither do men light a candle, and put it under a bushel, but on a candlestick; and it giveth light unto all that are in the house. Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven” (Matthew 5:14-15).

The harsh elements of life will eventually cause us to rust and wither away, but this is our eternally significant purpose as long as we remain standing. The “outer self” is wasting away, and it’s not as vigorous as it used to be (cf. 2 Cor. 4:16). Indeed, you will fade like flowers of the field, and your radiance will dim with time (Isaiah 40:7). Moreover, with each passing day, you are closer to the dust from which you came (Eccl. 12:7). But, as long as God keeps you upright in the world’s waters, your critical mission is to shine gospel light to those who grope in the darkness of sin (cf. 2 Cor. 4:6).

“O God, from my youth you have taught me, and I still proclaim your wondrous deeds. So even to old age and gray hairs, O God, do not forsake me, until I proclaim your might to another generation, your power to all those to come” (Psalm 70:17-18).
