"Here is the Icon of The Ladder of Divine Ascent which demonstrates the Orthodox view of "Theosis", what the West calls "Salvation". As you can see, it is an upward progress, but the icon shows that we can fall off the ladder through the efforts of the Evil One, which, by the way, is what the original Greek in the Lord's Prayer says, "but deliver us from the Evil One". The name of the icon refers to the book by St. John of the Ladder (Climacus) who wrote for his monks on how to attain theosis, becoming like God, about the year 600. St. John was the abbot of St. Katherine's Monastery at Sinai.
