Question: What is the resurrection of the soul, of which the Apostle speaks, saying, ‘If ye be risen with Christ’?, (Colossians 3:1).
Answer: When the Apostle said, ‘God, Who commanded the light to shine out of darkness, hath shined into our hearts’ (2 Corinthians 4:6) the resurrection, he showed this resurrection to be the exodus from the old state (which in the likeness of Sheol incarcerates a man so that the light of the Gospel will not shine mystically upon him. This is a breath of life through hope in the resurrection, and by it the dawning of divine wisdom shines in his heart), so that a man should become new, having nothing of the old man. This the prophet also says, ‘And I shall give them a new heart and a new spirit’ (Ezekiel 36:26). Then the image of Christ is formed in us through the Spirit of wisdom and the revelation of the knowledge of Him.
