As mentioned previously, one of the reasons Hashem may give a person suffering in this world is to save him from something far worse. Sometimes a person endures such hardship that he cannot imagine anything being worse. It is important to remember that there are endless reasons why a person may have to suffer, even if he is completely righteous. The Chovot HaLevavot in Shaar HaBitachon lists several possibilities and then cautions that we will never be able to determine why any individual is experiencing what he is going through. Hashem has a different calculation for every person, and only He knows the true reasons. What we do need to know is that whatever the reason may be, when a person eventually discovers why Hashem dealt with him this way — whether when Mashiach comes or when he reaches the next world — he will be grateful for every moment of the life Hashem gave him. If he can trust in Hashem now and accept it with joy even before understanding, his spiritual level will rise tremendously and his reward will be beyond imagination. One of the explanations given by the Chovot HaLevavot for why a tzaddik may suffer in this world is that through that suffering, Hashem grants him a far greater Olam Haba. We know from Chazal that even the faintest taste of Olam Haba is more pleasurable than all the delights of this world combined. And Olam Haba is eternal, while this world is temporary. But how does suffering here produce a higher Olam Haba? One explanation is based on the teaching of Chazal that one mitzvah performed with difficulty is worth far more than the same mitzvah performed easily. When someone is going through hardship, illness, or pain and still manages to perform a mitzvah, still manages to pray, still manages to learn, everything he does carries infinitely greater value. One minute of his avodah may outweigh hours of effortless service. Two people may be praying in the same shul, learning in the same class, appearing identical in this world. Yet in the next world, one may stand far higher than the other — because the effort required of him was so much greater. For him, getting to shul or opening a sefer demanded real sacrifice, while the other person had it easy. We do not ask for hardship, because we fear we may not accept it properly. But if hardship does come, we must understand that it carries within it a golden opportunity to earn reward beyond anything we can imagine. It may be that someone who appears to be an ordinary Jew in this world is in truth among the greatest of the generation — not because of how much he accomplishes , but because of what he must endure to accomplish whatever he does manage to accomplish. He keeps going with a smile. He keeps doing mitzvot even when it is painfully difficult. He keeps his emunah in Hashem even when life feels unbearably hard. This may also explain the Gemara which tells that when Rav Yosef became ill, his soul briefly departed and then returned. Afterward he said he saw an upside-down world — those who appeared lowly here were elevated there, and those who appeared elevated here were low there. His father told him, "You saw a clear world." A person who looks like a simple Jew down here may occupy the highest place in the upper world because of the enormous difficulty he faces in serving Hashem within the life he was given. There are infinite reasons for suffering in this world. For now, our task is to trust that every one of them is for the best. If a person can accept that Hashem is doing what is best for him and continue to serve Him with joy, he will merit the highest places in Olam Haba for all eternity.
