Have you been dishonored? Then have regard for the glory which is laid up in Heaven through patient endurance. Have you suffered a loss? Then contemplate the heavenly wealth and treasure which you have laid up for yourself through your good deeds. Have you been expelled from your homeland? Then you have Jerusalem as your heavenly homeland. Have you lost a child? Then you have Angels, with whom you will dance around the Throne of God, rejoicing eternally. By thus opposing anticipated good things to present sorrows, you will keep your soul in the cheerfulness and tranquility to which the Apostles precept summons us. Neither let the joys of human affairs create immoderate and excessive gladness in your soul, nor let sorrows diminish its exultation and sublimity by feelings of dejection and abasement. Unless you have previously trained yourself in this way regarding the eventualities of life, you will never have a calm and tranquil life.
But you will easily achieve this if you have dwelling within you the commandment which advises you always to rejoice, dismissing the vexations of the flesh and gathering that which gladdens the soul, transcending the sensation of present realities and extending your mind to the hope of eternal realities, the mere thought of which is sufficient to fill the soul with rejoicing and to make Angelic exultation reside in our hearts;in Christ Jesus our Lord, to Whom be the glory and the dominion, unto the ages. Amen.
