Hymn 184 from the Abridged St Alban Hymnal:
(Tune: Ellers)
Power of all Powers! O fill and flood my being;
O Sun Eternal, whelm me in Thy Light;
Vision itself need ask no eyes for seeing,
And boundless Life no wings to mount the height.
I am thy Light, by mortal lamp enshrouded;
Thy Bliss, beyond all shifting joys and pains;
Above their glooms and gleams is Peace unclouded,
Shatter the lamp; the Light, the Light remains.
Father of Spirits, Love forever burning;
Burn thou all forms that hold my Life from Thee,
Lost in my selfhood, to Thyself returning,
Find Thou Thine own and my Eternity.
Almighty Father, Maker and Destroyer,
All-glorious Son, our Master and our Friend;
Spirit of man, Inspirer and Employer;
We worship Thee in glory without end.
(This is one of my favourite hymns.)
