But we have Baptism, which reconciles us with God; why then do we need a special sacrament of Reconciliation?
Baptism does snatch us from the power of sin and death and brings us into the new life of the children of God, but it does not free us from human weakness and the inclination to sin. That is why we need a place where we can be reconciled with God again and again. That place is confession.
It does not seem like a modern thing to go to confession; it can be difficult and may cost a great deal of effort at first. But it is one of the greatest graces that we can receive again and again in our lifeit truly renews the soul, completely unburdens it, leaving it without the debts of the past, accepted in love, and equipped with new strength. God is merciful, and he desires nothing more earnestly than for us, too, to lay claim to his mercy. Someone who has gone to confession turns a clean, new page in the book of his life.
