Here's a quick little poem-prayer I wrote back when I was in college:
Benediction
May the peace of Christ be with you,
In
your comings and in your goings.
May the True Spirit direct the
journeying of your heart,
And
may His loving care enfold you.
May the Living God be your shield on
the day of battle,
And
may He defend you with His strong right arm.
Now and always, wherever you go.
Now, and always, wherever He leads
you.
Amen.
