Analysis of Evening on Calais Beach

IT is a beauteous evening, calm and free,
   The holy time is quiet as a Nun
   Breathless with adoration; the broad sun
Is sinking down in its tranquillity;
The gentleness of heaven broods o'er the sea:
   Listen! the mighty Being is awake,
   And doth with his eternal motion make
A sound like thunder--everlastingly.
Dear Child! dear Girl! that walkest with me here,
   If thou appear untouch'd by solemn thought,
   Thy nature is not therefore less divine:
Thou liest in Abraham's bosom all the year;
   And worshipp'st at the Temple's inner shrine,
   God being with thee when we know it not.
