The Shomer Emunim writes in his ma’amar on hashgacha peratit ( perek 6), any suffering that a person bears in this world, especially if he believes that it’s coming from Hashem and doesn’t question Him, then it will cleanse him from endless potential suffering in the Next World. If a person was able to see what he was gaining through each suffering in this world, he would dance with the greatest joy, realizing the unbelievable kindness that Hashem is bestowing upon him. The greatest gains from any affliction come about if the person accepts it with love. Fortunate is the person who accepts his suffering with love. Aside for the tremendous benefit it brings him, the Gemara in Ta’anit says, it is so powerful, it brings about salvations to the entire world. The Shomer Emunim writes further, if a person gets even a small affliction and instead of attributing it to happenstance, he recognizes it was from Hashem and he says, “I deserve this because of my sins,” and he asks Hashem to be forgiven, that would bring him forgiveness for all of the blemishes he created in the Upper Worlds, and all the judgments would then become sweetened for him and it will be considered as if he received much more suffering than he actually did. The angel that used to learn Torah with the Bet Yosef told him, on one occasion, the reason why his wife wasn’t having children. It had something to do with her neshama having a male element to it. But then he was told, because she went through certain sufferings and she accepted them happily, that made her soul so pure. Through that, she was zocheh to have children. A man once came to the Steipler Rebbe in need of chizuk due to all the problems he was experiencing. The Steipler told him not to dwell too much on the problems of this world. He went on to tell that man about all the problems he had. He said if he would have paid attention to all of his suffering, he would have remained an am ha’aretz , not learning even one page of Gemara . He said some of his problems were so great they could have been distributed to a hundred people and there would have been enough for all of them. Yet, because of his emunah, he knew all of his problems were sent by his loving Father Hashem, for his benefit, and that enabled him to move on each time with happiness. He grew in Torah, amidst the suffering, until he became the Gadol Hador. If people keep saying they are waiting for this problem to end, for that issue to become easier, they will be forfeiting their greatest opportunities for spiritual growth. We do hope the problems will become easier and go away, but in the meantime, if we persevere and continue fulfilling our roles as ovdei Hashem happily, we could reach the greatest heights. There are also great segulot involved in a person accepting what is happening to him with love. It brings about Heavenly mercy, it makes a person more fit for salvation, and most importantly, it purifies him and brings him to great spiritual levels. Chazal tell us, if Iyov wouldn’t have complained about his suffering, he would have risen to the level of our holy Avot, Avraham, Yitzchak and Yaakov. This is the awesome value of not complaining, and rather accepting that whatever is happening is happening because of Hashem and it is for our best. If when a person is going through troubles, he is able to continue on living happily and serving Hashem to the best of his ability, his rewards will be endless.
