The Mercy of the Tide

A complicated musing on insufficiency

Part 1 is here:

The Mercy of the Tide

“What profit hath a man of all his labour which he taketh under the sun? One generation passeth away, and another generation cometh: but the earth abideth for ever.”

— Ecclesiastes 1:3–4 (KJV)

Whatever we build is only sand holding back the ocean. The tide runs out, and in the damp sand we find the ability to create intricate beauty, towers, crenellations, a veritable fortress of a sandcastle complete with a moat and, given some seaweed and driftwood, a drawbridge. All day in the sun with joy we make it up and then, in the twelfth hour, the tide runs back in and overtakes it all. If we come back the next morning we are presented with a flat stretch of perfectly damp sand, no trace at all of the magnificence of our imagination remaining after the ocean’s touch. Shall we weep like children for the passing of the castle into the sea? Or begin anew with the blank canvas of the beach?

The sand itself teaches us the nature of time. It yields easily to our hands, holds every shape we press into it for a few bright hours, then surrenders completely to the sea. No monument we raise upon it lasts. The towers we labored over with such care are leveled without malice or memory. This is no punishment of our striving to create and build. It is the rhythm of creation under the sun. One generation builds its castles. The tide comes. Another generation finds the shore made smooth again. They are given room to put their own stamp on the world, to create their own personal castles and dreams.

There is a strange mercy in this daily erasure. The blank canvas of wet sand does not carry yesterday’s collapsed walls or yesterday’s disappointments. It simply waits, cool, receptive, and full of possibility. Each morning the ocean offers us forgetting, and with it, the chance to begin again. The sand has gone nowhere. The ocean simply reset it for another day.

The Preacher knew this long ago. All our labor passes, yet the earth abideth. Our works dissolve, yet the shore remains ready. We are not asked to build something eternal with perishable hands. We are invited, instead, to participate in the temporary with joy, to shape beauty for its own brief season, then release it when the tide calls it home.

This truth echoes through every stage of life. The dreams of youth are reshaped by time. The structures we carefully built in midlife, projects, plans, even parts of ourselves, slowly or suddenly wash away. Relationships change. Strength fades. What we once carried with ease becomes too heavy. Yet every season of loss is followed by a new stretch of damp sand. The question is never whether the tide will come. The question is whether we will return to the shore with open hands. With laughter, and bright buckets, and a dreaming vision of a different castle to build.

There is profound freedom in accepting this. We need not cling to yesterday’s castle, nor despair because it could not stand forever. We may grieve its passing. Then we may kneel again in the cool sand and begin. Perhaps this time the castle will be simpler. Perhaps it will be more beautiful for its modesty. Perhaps we will build it not for permanence, but for the pure delight of building while the sun is high and warms our bones while we age and yearn for the end of time and the promise of hereafter.

Yet even as we shape these fleeting castles, something deeper is being built. The true labor is not the vain repetition of sandcastles upon the shore, but the quiet, hidden work wrought in the soul. Character forged in the heat of the day. Love patiently tended through many tides. Trust and gentleness deepened through repeated release. Faith anchored not in the shifting sand, but in the One who made both the shore and the sea. These are the foundations that remain when all visible labor has washed away. These are the treasures laid up where neither moth nor tide can destroy them.

And so we walk the shoreline of our days. We build what we can while we can. We watch the tide do its ancient work. Then, in the quiet morning light, we begin again, trusting that the One who made both the sand and the sea also made room for renewal, and for something everlasting within us.

We can but pray we do not fail in this gentle labor: to shape beauty for a season, to release it with grace when the waters rise, and above all, to tend faithfully the deeper work of the soul. A prayer that rises, quiet and hopeful, even as the tide turns.
