For the Holy Spirit

Strengthen me, O God,
by the grace of your Holy Spirit.
Strengthen my inner man,
and empty my heart of all useless care and anguish.
O Lord, grant me heavenly wisdom,
that I may learn to seek and to find you above all things,
to relish and to love you above all things,
and to think of all other things
as being at the disposal of your wisdom.

For the Presence of the Holy Spirit

O holy Counselor,
sweetest consolation of the sorrowful,
gracious Spirit come down now with your mighty power
into the depths of our hearts.
Gladden there with your brightness every dark retreat,
and enrich all with the dew of your abundant comfort.
Kindle our hearts with holy favor,
that the incense of our prayers and praises
may ever go up to you, our God;
through Jesus Christ your Son our Lord. Amen.

Litany Prayer for True Worship

O God,
you have commanded us to worship you in spirit and in truth.
Overshadow us with the power of your Holy Spirit.
Let your mercy and the gracious promise of your salvation come to us,
that our prayer may be directed to you by Christ,
through whom our sins are forgiven.
Hear us, O Lord. Amen.

For the Holy Spirit

Almighty God,
kindle our souls by your Spirit,
that being filled with your divine gifts,
we may shine like blazing lamps
in the presence of your Son Christ at his coming;
through the same Jesus Christ our Lord. Amen.
