The following prayer of St. Augustine, like that of St. Ephraim, is in accord with the spirit of Lent. Enjoy!
the house of my soul is narrow;
enlarge it that you may enter in.
It is ruinous, O repair it!
It displeases your sight.
I confess it, I know.
But who shall cleanse it,
to whom shall I cry but to you?
Cleanse me from my secret faults, O Lord,
and spare your servant from strange sins.
(This prayer is taken from the section “Prayer and Hymns for Lent” from the iPhone application iBreviaryPro.)
