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.
