There is another type of sinful sorrow, but which is also a result of seeing one's own soul in it's true sinful form. This is the sorrow of Judas; not Peter. Both have wronged against the Lord – Peter has renounced him, Judas has sold him. But Peter was forgiven, because he had repented, Judas did not. Judas, not believing in the mercy of God, his love and goodness, trusted that he was too much sinful to be saved. We cannot judge him, for many of us are a victim of such thoughts – but we have to say that it is very much a sin! We must remember that God loves us more than the devil hates us, in the words of Origen. We cannot fathom how much God loves us. No matter how much we stray, like the prodigal son, he will always knock on the door and wait. But the demons, being trained and experienced in combat with the human soul, use a cunning tactic; before we commit sin, they suggest that God is loving and forgiving. After we commit sin, they suggest he is righteous and just, and we will not be pardoned for our sin.
There is a sorrow which is present in every human being. To understand it, we need to take a look back at Adam's state in Eden.
Father Siluan, Adam's Lament
"Adam, our forefather, knew the pleasure of God's love in Eden. His soul was torn apart by the thought "I've betrayed God, whom I love so much." Adam wasn't that hurt by not being in Heaven, surrounded by beauty, but he was more hurt by losing God's love. In this case, every soul feels pain and immense sadness.
(…)
"..I have much wept over betraying God, over my sin and ultimately losing peace and love which inhabited the Earth. Tears have run down my face and watered the earth. The desert has heard my cries. You cannot understand my sadness, nor my lamentations. I used to be careless and happy in Heaven. The Holy Spirit embraced me and i did not know of suffering. But when i was exiled, the cold began to bother me. The beasts which used to be harmless and which were obedient to me, began to fear me. Evil thoughts corrupted my mind. The sun and the wind kept torturing me."
There we see the pain which the Godless soul keeps inside. Every man has experienced this, and many now experience it. Thank the Lord, for he has brought us a Redeemer to appease for our sin. Christ, with his sacrifice on the Cross, opened up the path to God again, he has defeated Satan, he has righted Adam's wrong. Some even suggest that he would come to the world even if Adam did not sin.
Still, there is one more problem – even with Christ as a sacrifice and the path to Heaven opened up again. Our own personal sin. If God looked at our sins, we surely wouldn't be worthy of union with Him. We surely would not be worthy of salvation. But God, in his wisdom, has established the ritual of Confession. Confession is the way we wash ourselves of sin and reach forgiveness. If there was no Confession, there would be no forgiveness, therefore, no one would be saved.
Woe to us, because we rarely confess, and when we do, we do it without any feeling of repentance! And what would our forefather Adam give back then for the absolvement of his sins? We can only trust in the Mercy of God, for if he looked upon the entirety of our sins, we would surely be damned.
(I didn't think this through, should have written it all in notepad and then pasted it but oh well)
