I believe that in the anticipation of God's hour, the hour of peace and light, you must not give in to dark thoughts. (…) I think that this trust in God, who gloriously leads you through dark and difficult paths to His divine center – you, who are becoming more beautiful and successful in His eyes each day – can be found in an ever-deepening connection with our Lord, whom you can seek in faith and perseverance in the Eucharist, sense and love in His Will, as it reveals itself to you, humbly asking Him to place His hand upon your eyes and draw you to Himself with His arms.
