And though I ebb in worth, I'll flow in thanks.

The line hinges on a water metaphor—“ebb” and “flow”—to contrast diminishing personal “worth” (status, strength, fortune, or merit) with an undiminished, even increasing, capacity for gratitude. It suggests a speaker who anticipates decline yet refuses bitterness: if circumstances or self-estimation recede like a tide, thankfulness can still rise. The phrasing implies a moral stance that gratitude is not contingent on prosperity or self-importance; it can be a deliberate counter-current to loss. In a broader literary tradition, the sentiment aligns with devotional and stoic strains in English verse that treat thankfulness as a discipline maintained under adversity.
