How does Coleridge describe the state of the mariner now? In what ways is this a contrast to his previous state

Until the end of Part 5, it seems as though the Ancient Mariner is redeemed. Not only is he allowed to sleep, but it finally rains, and his thirst is quenched. Since physical drought and thirst have represented the Ancient Mariner's moral depravity up until this point, it is implied that the abundant rain symbolizes his redemption. According to a Christian interpretation, the rain signifies that he is being baptized anew as a righteous servant of Christ who respects God's creatures.
