They shall walk with Me in white: for they are worthy.@Revelation 3:4
William Cowper (1731-1800)

William Cowper, in Conyerโ€™s Collection of Psalms and Hymns, 1772. About these lines, Cowper wrote to his aunt: I began to compose them yesterday morning before daybreak, but I fell asleep at the end of the first two lines. When I awaked again, the third and fourth verses were whispered to my heart in a way I have often experienced.

Caithness Scottish Psalter, 1635 (๐Ÿ”Š pdf nwc).

O for a closer walk with God,
A calm and heavenly frame,
A light to shine upon the road
That leads me to the Lamb!

Where is the blessedness I knew,
When first I saw the Lord?
Where is the soul refreshing view
Of Jesus, and His Word?

What peaceful hours I once enjoyed!
How sweet their memory still!
But they have left an aching void
The world can never fill.

Return, O holy Dove, return,
Sweet messenger of rest;
I hate the sins that made Thee mourn
And drove Thee from my breast.

The dearest idol I have known,
Whateโ€™er that idol be
Help me to tear it from Thy throne,
And worship only Thee.

So shall my walk be close with God,
Calm and serene my frame;
So purer light shall mark the road
That leads me to the Lamb.
