"Fire and water do not mix, neither can you mix judgment of others with the desire to repent. If a man commits a sin before you at the very moment of his death, pass no judgment, because the judgment of God is hidden from men. It has happened that men have sinned greatly in the open but have done greater deeds in secret, so that those who would disparage them have been fooled, with smoke instead of sunlight in their eyes."
-St. John Climacus
"As a handful of sand thrown into the ocean, so are the sins of all flesh as compared with the mind of God."
"Just as a strongly flowing fountain is not blocked up by a handful of earth, so the compassion of the Creator is not overcome by the wickedness of his creatures."
"Someone who bears a grudge while he prays is like a person who sows in the sea and expects to reap a harvest."
-St. Isaac The Syrian
The greatest balm that Christ's sacrifice on the Cross gave us is the crushing of the devil. After the Crucifixion of Christ, the devil is like a snake with no fangs, with no poison; he is like a wild dog without teeth. All poison was removed from the devil; all teeth were removed from the wild dogs that are the demons. So, they are now disarmed; while we are armed with the Cross.
-Elder Paisios of the Holy Mountain, Athos
