We in the West have generally grown up thinking of sin as committing acts contrary to some kind of code, or list, of Bad Things that must not be done. But the Desert Mothers and Fathers don't seem to have looked at sin like this at all. The Greek word used for sin, αμαρτία - amartia, apparently means something much more like "missing the mark" than "doing bad stuff", as does the equivalent Hebrew term, syn. Irma Zaleski says, "They were thinking of the condition of those who are... not centred rightly, who are not in the right relationship with God. The root of sin - the ground from which all individual sins spring - is our alienation from God. Repentance, then, should not be... viewed primarily... in terms of guilt - of punishment and repayment - but in terms of metanoia: a Greek word meaning "conversion"... turning away from ourselves and recentring ourselves on God."
If we can get past the musty atmosphere of "owning up" which we have come to associate with repentance, and see it as taking an accurate view of ourselves in relation to God, and in relation to what we ourselves could be were we only open to love God as God loves us, then we begin to see that there really is very little difference between us and anyone - anyone - else. The seeds of cruelty and selfishness are sown deeply in all our hearts, and we cannot stand in judgement over another, no matter what they have done. This is hard, not only to identify with the pain of the victims, but with the cruelty of the victors and the perpetrators of darkness.
The way of the Jesus Prayer has been called "white martyrdom." It is the way of the Cross, because there is no greater pain than to stand in the total poverty of our human weakness, to see clearly our misery, our inability to be good. The temptation to judge ourselves, to hate ourselves, would be irresistible if we did not know and had not experienced the merciful, healing power of Jesus.
But, because we have met Christ and have experienced his compassionate, loving presence, we can surrender all judgement to him and be at peace. We can accept ourselves as we are. We can love ourselves and also love others. Because we have discovered that the judgement of Christ is not the judgement of an inquisitor or a tyrant but of a Good Physician, we are able to go to him and show him all the bleeding, cancerous places of our bodies and souls - not so he may punish us, but so he may heal us.The longer we go on walking in the way of the Prayer, the more clearly we realise that the gulf we have discovered separating us from God is the same gulf that separates our neighbours from God, and the longing for God that leads us onwards is the same longing, the same sense of incompleteness, of - as the existentialists termed it - alienation, that drives the restless and destructive addictions of humanity.
Once realised, once seen for what it is in the bright Light that the Spirit shines into our deepest hearts, this sadness of separation - the core of true repentance - becomes a spring of tears, welling up for ourselves and for all people. It may be sadness, but it is what St John Climacus called "a bright sadness". And we see that our separation is not different from that separation of anyone, and that our prayer for mercy, for union, for reintegration with God, carries with it the love, and the pain, that God has somehow through all this given us for all who suffer, human or otherwise, pain and separation. Our praying of the Jesus Prayer has become in itself intercession: as the writer of the Letter to the Hebrews wrote: "[Christ] is able for all time to save completely those who approach God through him, since he always lives to make intercession for them." (Hebrews 7.25)
