If someone wishes to love himself he must not allow himself to be corrupted by indulging his sinful nature. If he wishes to resist the promptings of his sinful nature he must enlarge the whole horizon of his love to contemplate the loving gentleness of the humanity of the Lord. Further, if he wishes to savor the joy of brotherly love with greater perfection and delight, he must extend even to his enemies the embrace of true love. But if he wishes to prevent this fire of divine love from growing cold because of injuries received, let him keep the eyes of his soul always fixed on the serene patience of his beloved Lord and Savior.
