The prayer of St. Francis before this crucifix, San Damiano, Italy:
All-highest, glorious God,
cast your light into the darkness of my heart.
Give me right faith,
and profound humility,
with wisdom and perception, O Lord,
so that I may do
what is truly your holy will.
This is a slightly different translation than the one I usually pray, and I thought it was beautiful. I deeply need this prayer today, and the guidance of the Holy Spirit.
