Be Thou My Vision - Definitely one of my favorite hymns, even favorite songs. I've heard lots of good versions of this song.

 

Be Thou my vision, Oh Lord of my heart
Naught be all else to me save that Thou art
Thou my best thought by day or by night
Waking or sleeping, Thy presence my light.

Be Thou my wisdom and Thou my true Word
I ever with Thee and Thou with me Lord
Thou my great Father and I Thy true son
Thou in me dwelling and I with Thee one.

Be Thou my breastplate, my sword for the fight
Thou my whole armour and Thou my true might.
Thou my soul's shelter and Thou my strong tower
O raise me heavenward, great Power of my power.

Riches I heed not, nor man's empty praise
Thou mine inheritance now and always
Thou and Thou only first in my heart
High King of Heaven, my treasure Thou art.

High King of heaven, my victory won,
May I reach heaven's joys, O bright heav'n's Sun!
Heart of my own heart, whatever befall,
Still be my vision, O Ruler of all.
