Depression is often inseparably connected with a consciousness of sin.  Whether it is deserved or not, the feeling of being guilty is part of the deepest burden a person can carry.  "I cannot forgive myself" is a comment often heard.  When God forgives us then we can also forgive ourselves, we must forgive ourselves.  This belongs to proper humility.
In this connection the previously mentioned example of a contract from Willi Lambert  pertains.  God has forgiven us and we must now forgive ourselves like the required counter signature on a contract.  When we don't accept the "counter signature" that allows us to be forgiven, the forgiveness of God also can not work in us.

- Matthew 18:21-35 (Parable of the Ungrateful Servant/ Of the unmerciful believer)

We can meditate on this parable in the light of whether we can forgive ourselves and how we can do that.

- The comment of a four year old boy: "The big Devil can't do anything to me because I'm so  little!"

- Word meditation:

„The spiritual life is not a superficial layer of our being - a kind of cloak that covers and stretches over everything so as to cover the unconscious, the psyche, and "hide" us, so to speak.  It is rather the reverse I would say.  Grace goes much deeper than our unconscious self.   Of everything in us it is the deepest aspects that must permeate the body and the psyche. Generally this uproots, wounding and healing, breaking up and building again, putting things straight.

The entire person must be healed and rescued in this way.  This breakthrough of grace is also a breaking up.  It is always painful.  It brings a person to their most profound weakness, to their deepest point, to their zero point... The decisive spiritual test... that happens in life... is to loose one's reason on the edge of despair, on the threshold of possibility.  It can go so far that [the person] is not rescued from his/her deepest weakness.  That is not surprising for when the walls of false humility and false fulfillment are demolished then everything becomes possible again.  The person is completely delivered from his/her fear.  Here no ideal can help, but here God is present in a new way.  Here God shows merciful love.  As Paul said, in our deepest weakness God's grace will become strength.  This staying in weakness and being accepted by saving love is the grace of humility.  It is a wonder.  It is the miracle plain and simple that brings persons to peace; that allows them to find their balance; that leads them into deep unity reconciling their disunity; that leads to deep union and reconciliation with God and with all their brothers and sisters.  It is truly  a wonder.“        (André Louf)

Suggestion:  In meditation limit  yourself to what you remember after a slow and thorough reading of the text...(do not continue to reread text during meditation, however).
