As we begin the season of Lent, we give thanks to God the Father for this time of grace.  Let us ask him to cleanse our hearts and strengthen us in love through the Holy Spirit.
(From The Intercessions,
Ash Wednesday, Morning Prayer,
The Divine Office)

If we say we have no sin, we deceive ourselves, and the truth is not in us.  If we confess our sins, he is faithful and just, and will forgive our sins and cleanse us from all unrighteousness.
(1 John 1:8,9)
