One use of parables is to provide an earthly image of a spiritual concept. The parables for this week focus on forgiveness and how the Lord continually forgives us.
What does retrieving what was lost teach us about forgiveness?
AC 9014.3. The Lord forgives everyone his sins, because He is mercy itself. Nevertheless they are not thereby forgiven unless the man performs serious repentance, and desists from evils, and afterward lives a life of faith and charity, and this even to the end of his life. When this is done, the man receives from the Lord spiritual life, which is called new life. When from this new life the man views the evils of his former life, and turns away from them, and regards them with horror, then for the first time are the evils forgiven, for then the man is held in truths and goods by the Lord, and is withheld from evils. From this it is plain what is the forgiveness of sins, and that it cannot be granted within an hour, nor within a year. That this is so the church knows, for it is said to those who come to the Holy Supper that their sins are forgiven if they begin a new life by abstaining from evils and abhorring them.
