…In the words of St. John Climacus, “Repentance is the daughter of hope and the denial of despair.” It is not despondency but eager expectation; it is not to feel that one has reached an impasse, but to take the way out. It is not self-hatred but the affirmation of my true self as made in God’s image. To repent is to look, not downward at my own shortcomings, but upward at God’s love; not backward with self-reproach, but forward with trustfulness. It is to see, not what I have failed to be, but what by the grace of Christ I can yet become.
When interpreted in this positive sense, repentance is seen to be not just a single act but a continuing attitude. In the personal experience of each person there are decisive moments of conversion, but throughout this present life the work of repenting remains always incomplete. The turning or recentering must be constantly renewed; up to the moment of death, as Abba Sisoes realized, the “change of mind” must become always more radical, the “great understanding” always more profound. In the words of St. Theophan the Recluse, “Repentance is the starting point and foundation stone of our new life in Christ; and it must be present not only at the beginning but throughout our growth in this life, increasing as we advance.
