The people that walked in darkness have seen a great light: they that dwell in the land of the shadow of death, upon them hath the light shined.@Isaiah 9:2

Henry Coward (1849-1944)

How heavy is the night
That hangs upon our eyes,
Till Christ, with His reviving light,
Over our souls arise!

Our guilty spirits dread
To meet the wrath of Heaven:
But in His righteousness arrayed,
We see our sins forgiven.

Unholy and impure
Are all our thoughts and ways;
His hands infected nature cure
With sanctifying grace.

The powers of hell agree
To hold our souls in vain;
He sets the sons of bondage free,
And breaks th’accursèd chain.

Lord, we adore Thy ways
To bring us near to God;
Thy sovereign power, Thy healing grace,
And Thine atoning blood.
