Lyrics:Lord Jesus Christ, be present now;
Our hearts in true devotion bow.
Your Spirit send with light divine,
And let your truth within us shine.
Unseal our lips to sing your praise
In endless hymns through all our days;
Increase our faith and light our minds;
And set us free from doubt that binds.
Then shall we join the hosts that cry,
"O holy, holy, Lord Most High!"
And in the light of that blest place
We then shall see you face to face.
All glory to the Father, Son,
And Holy Spirit, Three in One!
To you, O blessed Trinity,
be praise throughout eternity!
