Be Thou My Vision

Over the past few days, I've had the words of this great hymn running through my head:

Be thou my vision, O 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 work
I ever with thee and thou with me, Lord;
thou my redeemer, my love thou hast won,
thou in me dwelling, and I with thee one.

Riches I heed not, nor vain, empty praise,
thou mine inheritance, now and always:
thou and thou only, first in my heart,
Great God of heaven, my treasure thou art.

Great God of heaven, my victory won,
may I reach heaven's joy, O bright heaven's Sun!
Heart of my own heart, whatever befall,
still be my vision, O Ruler of all.
