with Thee one

 We sang this hymn at Mass today and it came to me that if an explanation of the goal of the Christian life was wanted, this would do it.

Be Thou My Vision

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 Word;
I ever with Thee and Thou with me, Lord;
Thou my great Father, I thy true son;
Thou in me dwelling, and I with Thee one.

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.
