"How often shall we forgive? Until seven times? Until seventy times? How often shall we forgive, Master?"
"How often shall you forgive? Forgive until seventy times seven."
—-Recorded Conversation Between Jesus, the Christ, and One of His.
The point of forgiveness is not quantity but quality. Forgiveness is not just offered mindlessly, over and again. Forgiveness is an expression of the inner nature of the Forgiver and not the worthiness of the Forgiven.
This is quite because sin is never a matter of knowledge but always a matter of the will. The will is what we are inwardly. God constantly forgives because it is the nature of God to forgive. Those who receive divine forgiveness do not suddenly become worthy of mercy. Mercy is not mercy if we deserve it.
Divine mercy is the final cure of narcissism. Just as Orpheus is said to descend into Hades to steal away Eurydice from Pluto, so does divine mercy enter the actual Hell to preach deliverance to the captives there. Man always wants a Rescuer. Man always wants to be a Rescuer. Divine mercy is God's rescue vessel, available to deliver us from merciless self-absorption.
