O Thou who cam­est from ab­ove,
The pure ce­les­ti­al fire to im­part,
Kindle a flame of sac­red love
Upon the mean al­tar of my heart.

There let it for Thy glo­ry burn
With in­ex­ting­uish­able blaze,
[or, Unquenched, un­dimmed, in dark­est days]
And tremb­ling to its source re­turn,
In hum­ble prayer and fer­vent praise.

Jesus, con­firm my heart’s de­sire
To work and speak and think for Thee;
Still let me guard the ho­ly fire,
And still stir up Thy gift in me.

Ready for all Thy per­fect will,
My acts of faith and love re­peat,
Till death Thy end­less mer­cies seal,
And make my sac­ri­fice com­plete.
