O Splendor of God’s glory bright,
from light eternal bringing light,
O Light of light, light’s living Spring,
true Day, all days illumining.
Come, very Sun of heaven’s love,
in lasting radiance from above,
and pour the Holy Spirit’s ray
on all we think or do today.
And now to thee our pray’rs ascend,
O Father, glorious without end;
we plead with Sovereign Grace for pow’r
to conquer in temptation’s hour.
Confirm our will to do the right,
and keep our hearts from envy’s blight;
let faith her eager fires renew,
and hate the false, and love the true.
O joyful be the passing day
with thoughts as pure as morning’s ray,
with faith like noontide shining bright,
our souls unshadowed by the night.
Dawn’s glory gilds the earth and skies,
let him, our perfect Morn, arise,
the Word in God the Father one,
the Father imaged in the Son.
