you are great in power,
unsearchable in understanding,
and wonderful in your plans for us.
Fill your servant with the gift of the Holy Spirit
that he may stand before your holy altar blameless,
to announce the gospel of your kingdom,
to administer the Word of your truth,
to offer gifts and spiritual sacrifices to you,
and to renew your people in the font of rebirth,
that when your only Son,
our great God and Savior Jesus Christ, comes again,
by your mercies he will receive your reward;
for your holy and majestic name is blessed and glorified.
