O Lord, who hast mercy upon all,
take away from me my sins,
and mercifully kindle in me
the fire of thy Holy Spirit.
Take away from me the heart of stone,
and give me a heart of flesh,
a heart to love and adore Thee,
a heart to delight in Thee,
to follow and enjoy Thee, for Christ's sake, Amen
St. Ambrose of Milan (AD 339-397)
O Lord,
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.
St. Augustine of Hippo (AD 354-430)
