Who is First Friend Who Quotes Scripture from A Grief Observed and what is their importance?

One friend in whom Lewis had apparently confided some of his frustration with his reality quotes the scripture to him, saying, "do not mourn like those who have no hope". The friend had intended to offer comfort and reassurance of God's promises for eternity, but Lewis points out its inability to offer the comfort he wants. He will, as will all mourners, have to allow to die in himself the part of him that loved and needed his wife, just as a mother who loses her child will have to let the mothering part of her wither away for lack of an object.
