Wednesday of the 2nd Week of Advent

Here is the Collect for Wednesday of the 2nd Week of Advent.

COLLECT:
Omnipotens Deus, qui nos praecipis
iter Christo Domino praeparare,
concede propitius, ut nullis infirmitatibus fatigemur,
qui caelestis medici consolantem praesentiam sustinemus.

This prayer is ancient, from Rotulus 6 published together with the Veronese Sacramentary.

Notice the image of Christ as medicus, physician.  

English translation?

I think maybe some of you might take a crack at it today.
