Behold the Lamb of God!

Here is a hymn that I don't know. I was curious about it when I saw the title on Cyberhymnal. I liked what I saw, so here it is.

Behold the Lamb of God!
O Thou for sinners slain,
Let it not be in vain
That Thou hast died:
Thee for my Savior let me take,
My only refuge let me make
Thy piercèd side.

Behold the Lamb of God!
Into the sacred flood
Of Thy most precious blood
My soul I cast:
Wash me and make me clean within,
And keep me pure from every sin,
Till life be past.

Behold the Lamb of God!
All hail, incarnate Word,
Thou everlasting Lord,
Savior most blessed;
Fill us with love that never faints,
Grant us with all Thy blessèd saints
Eternal rest.

Behold the Lamb of God!
Worthy is He alone
To sit upon the Throne
Of God above;
One with the Ancient of all days,
One with the Comforter in praise,
All Light and Love.
