As I have mentioned earlier, much has been written about mercy. The Bible speaks about it some 250 times. Sister Faustina devoted much of her life to it. Yet, no one has a monopoly on it. Mercy is not just for a special few.
Mercy is for all that seek forgiveness of sins with a heart that desires change.
In this change of heart, we seek not to do our will any longer, but to do the will of our Father who art in heaven. Then our Father who art in heaven will see us and being moved with compassion, He will remember our sin no more. In this we surrender and conform ourselves to the will of God, that His will be done on earth as it is in heaven.
