Be Thou My Vision was my favorite hymn in my church going days. Posting a video of a peaceful version in Irish Gaelic since it's based on a Middle Irish poem.
These lyrics are the ones we used based on the 1912 English version by Eleanor Hull. Though I'm closest to a sort Christian Agnosticism these days, I still love the heart of the prayer.
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.
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.
(The English Methodist version from 1964 omits verse 3.)
