Whether you choose to sacrifice or to engage in an additional spiritual activity during the season, remember its purpose. To assist, a website (d365), is offering daily devotionals (with email reminders). d365 is an ecumenical effort between Presbyterian, Episcopal, and Baptist groups.
I leave with the words of St. Augustine of Hippo (AD 354-430):
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.
