O God, our Saviour, Who wast well pleased to guard the travels of Thy holy apostle Paul on the highways of the earth, and didst thereby bring the Gospel of salvation to a pagan world: do Thou Thyself now also preserve unharmed them that desire to venture upon the perilous network of our day.  Be Thou the guardian of our eyes and rational mind, and preserve our spiritual heart in stillness all the days of our life.  For unto Thee are due all glory, honour, and worship, together with Thy Father Who is without beginning, and Thy most-holy, good, and lifegiving Spirit, now and ever, and unto ages of ages.  Amen.
