O God, the Protector of all that trust in Thee, without whom nothing is strong, nothing is holy, increase and multiply upon us Thy mercy; that, Thou being our Ruler and Guide, we may so pass through things temporal that we finally lose not the things eternal. Grant this, O heavenly Father, for Jesus Christ’s sake our Lord. Amen.
