The grief you feel is real, but you must consider what has truly been taken from you. The thief has deprived you of things that are without you, and that hereafter would spring away from you even against your will. But how does the loss become grievous? When you lose your soul! Tell me, the thief has taken your phone: will you deprive yourself of salvation? Wherefore, grieving at the evils which you have suffered from another, do you plunge yourself into more evils? He has involved you in this sorrow, but if you perversely injure yourself in things that are fatal, you give the devil his delight. He has grieved you by taking away these sentimental things; do you grieve him, and do not delight him. If you render thanks to God, you give him his death blow.
You say the authorities are lazy, that the thief could be caught easily, and this makes you feel hopeless. Here then is a lesson: be not wise in your own conceits. Do not think you can do for yourself or that you perceive all that is needful. There is nothing that so elates men and makes them feel different from others as the notion that they can see the whole matter clearly and judge it rightly. But God has placed us in need of one another, and though you are certain this should be resolved by your own understanding of how easily the evidence points the way, you may not perceive what is truly needful. This helplessness does not lower you; it exalts you, making you stronger and more secure, for it forces you to cling not to your own wisdom but to God who works through even the negligence of men.
And that thought which creeps in, "does this all even matter?" Do not feed yourself with cold hopes or empty despair. You say you hope this brings you closer to Abba, and that is exactly the matter. For what is the loss of sentimental items, what are these shadows, compared to the excellency of the knowledge of Christ Jesus the Lord? Paul counted all things but loss, yea, as dung, that he might gain Christ. The phone held memories, but Christ is the eternal memory of the Father. If the loss of these transitory things draws you away from Him, it is indeed a loss. But if it sends you on to Him, if it makes you see that nothing here is permanent and that your true treasure lies only in heaven, then the loss itself becomes gain. When the sun has appeared, it is no loss to sit by a candle, but a foolishness to mourn the candle.
Do not then suppose that this comfort and direction from God you seek is for monks only, because you have the cares of a household. This is what has ruined all, your supposing that the reading of the divine Scriptures and the seeking of deep wisdom belong to those only. You dwell in the world and each day receive wounds; you have most need of medicines. The Scriptures are written for our admonition. Take them up. Let their medicine heal this wound.
And after prayer thus intense, there is need of much almsgiving: for this it is which especially gives strength to the medicine of repentance. You have been wronged, yet give alms. Water will quench a flaming fire, and alms will do away with great sins. By this act, you show the devil that he has taken nothing essential, for you still have the eternal riches to give away. This is how you turn sorrow into the deathblow of the enemy, how loss becomes the ladder by which you ascend closer to God. Pray, give thanks, show mercy to another who has lost more, and you will find the perspective you seek. The sentimental items are gone, but the eternal love of Christ cannot be stolen. Let this truth be the direction you ask for.
