A mystagogical quintology

Illuminates your eager wasteland, you are great;
But wretchedness is expressed in all your waves,
And then we know you and the longing you have.
O, for the footsteps of the Prince of Peace
A title for Jesus Christ, derived from Isaiah 9:6.
To still your tumult, and His voice to quiet
Our stormy hearts! There is no help in you;
Our need is yours, and what you are, O sea,
All nature is: a message to the soul,
Sometimes a relief, and sometimes a service,
But not true rest or true beatitude!
Supreme blessedness or perfect happiness.
Yet in the sweet peace of a day to come,
There shall be no more sea of storm and pain,
But splendid calm, clarity, and depth,
With gladness in an immensity like yours,
O royal ocean, whom we hail and love!
