The theme of the ladder from the Christian perspective addresses "moral life in the context of the last judgement. The ladder charts moral growth. The original idea comes from Jacob's ladder in the Old Testament. The St John Climacus ladder became popular in the east and St Benedict's ladder in the West. There are a number of other ladders and they all have one theme: How do we live our lives so that we will go to heaven and avoid falling to hell" (eXw studies, A2ki).
