So his love to Christ endure?

When the shore is won at last,

Who will count the billows past?

The first four lines resemble a stanza of Wither, one of the Roundhead poets (1632):—

Whether thrallèd or exiled,

Whether poor or rich thou be,

Whether praisèd or reviled,

Not a rush it is to thee:

This nor that thy rest doth win thee.

But the mind that is within thee.
