Is a person tested with a task beyond his ability? Two opposing views

The question has been raised as to whether G-d gives us tasks that we can't succeed and that failure is inevitable. There seem to be two different views.

Obligations are given only if it is possible to succeed - one cannot fail a task

Kesubos(67a): According to the camel is the load.[A camel is given a burden according to how strong it is- Rashi]

Bereishis Rabbah (32:3): A potter does not test defective vessels because he cannot even give them even a single blow without breaking them. Similarly G‑d does not test the wicked but only the righteous. When a flax worker knows that his flax is good then he knows that the more he beats it the more it improves. In contrast when he knows that it is poor quality he doesn’t bother beating it because he knows it will simply split. Similarly G‑d does not test the wicked but only the righteous. When a person has two cows one of which is strong and the other weak, obviously he puts the yoke on the strong one? Similarly G‑d does not test the wicked but only the righteous.

Rav Saadiya Gaon(Emuna V’De’os 5:3): The righteous suffer for two reasons. The first reason is that it is for the few sins they have committed… The second reason is that it a trial. G‑d tests them when He knows that they will be able to endure the suffering. Afterwards he will reward them to compensate them for the undeserved suffering. G‑d does not test a person who cannot endure it - because then it serves no purpose. The purpose in afflicting the righteous is in order that mankind should know that G‑d did not choose them for nothing. Job and his suffering is an example of this second type of suffering. If the suffering is the result of sin then typically G‑d will acknowledge that this is the reason - if He is asked. On the other hand if the suffering is because it is a trial - G‑d typically does not acknowledge it. This we see from the response to Moshe’s complaint “Why are you making it worse for this people.” Similarly Job was not answered when he asked why he was suffering. This lack of explanation is necessary so that the suffering of the righteous should not be simply dismissed by the average man as merely a means for the tzadik of getting additional reward. And I say that even the completely innocent person is sometimes afflicted in order that he gets reward for it. This is obviously the case for the infant who suffers. I have no doubt that they will be compensated for their suffering. A wise person views suffering as the chastisement of a father by means of a beating or detention to keep his son from harm. It is comparable to the disgusting bitter medicine that a person takes to be cured. A person might ask why is this suffering necessary because G‑d can give the good without the suffering? We answer him that good deservedly given as reward is better than receiving it out of kindness.

Impossible tasks are given which cannot be accomplished - we must fail sometimes in life

Ksav Sofer (Vayikra 10:1): And they offered before G‑d an unauthorized fire which He had not commanded them. Question: The Tanchuma (Achrei Mos #8) says that Aaron’s sons died because they didn’t get married and didn’t have children. Furthermore it says that they walked behind Moshe and Aaron and said, “When are these old men going to die so that we can take over the leadership of the community?” It is necessary to understand this medrash since it does not seem to fit in with the Torah which gives the explicit reason for their death as being punishment for offering an unauthorized fire before G‑d?  It is also astounding that these righteous men - who were in fact greater than Moshe and Aaron according to Rashi (10:3) – should transgress G‑d’s command and not fulfill the mitzva of having children and also that they would speak in such an arrogant manner – “when are these old men going to die?” Answer: It appears to me that the reason that they didn’t get married is that they saw that Moshe’s children did not turn out properly as is well known. If Moshe’s sons were not fit then they felt that a lesson could be learned that surely would apply to the masses. They ascribed the failure of Moshe’s children to the fact that Moshe was constantly preoccupied with the problems of the community and therefore he didn’t have the ability to properly supervise his children. (We see a similar judgment of Chazal regarding the children of Shmuel who did not go in his righteous path because he was constantly involved with community problems.) In contrast Aaron’s sons were great tzadikim because Aaron was not so much preoccupied with the community and thus was successfully able to supervise his children. On the other hand Aaron himself never reached Moshe’s spiritual level because his energy was devoted to his family. Being aware of this they decided that the best solution to the inherent contradiction between serving the needs of the community and the needs of the family - was not to get married. They were fully aware that with the death of Moshe and Aaron they would become the leaders of the community. They reasoned that if they had children they would not be able to supervise them properly and they would end up going in the wrong path. Or if they took the path of Aaron and properly supervised their children – then they would not be able to devote the needed time to leading the community. Consequently they decided the best way to serve G‑d and His people was not to get married. We need to add two other aspects from the medrash regarding their following after Moshe and Aaron and saying “When are they going to die?” It doesn’t mean chas v’shalom that they were looking forward to their deaths or that they were discussing between themselves that when they would die they would become the leaders. The medrash means to describe that they were concerned with understanding what Moshe and Aaron lacked. Moshe was very concerned with the needs of the community and therefore he had children who were not good. Aaron who supervised his children did not have so much time for the community and therefore he did not have the merit of serving the masses so much. Therefore Aaron’s sons concluded that they should get married. In truth they erred in this conclusion. Because “what business did they have with G-d’s secrets.” Their job was not to second guess what G-d wanted. Their job was to fulfill His mitzvos which clearly commanded them to have children. (We find a similar mistaken understanding described in Berachos (10a) concerning King Chezkiyahu. He also didn’t have children because he knew through the power of prophesy that his children would be wicked. However this was a mistake and his father-in-law, the prophet Yeshayahu, was sent to him with the message,”You will die now in this world and you will not have any portion in the next world because you didn’t have children.” Yeshayahu rejected Chezkiyahu’s justification that his children would be wicked people by saying, “What business do you have with G-d’s secrets?”). Thus we see that Aaron’s had a strong passion for loving G‑d and His people and therefore they decided that to be successful as leaders and serving G-d it was best not to have children. This in fact was the “unauthorized fire” which they had not received from G-d. They in fact had not been commanded to lead the people in a manner that differed from Moshe – but they were required to fulfill G‑d’s commandments and get married and have children. Thus this mistaken idea was the “unauthorized fire” and it was the reason why they died. So even though their motivation was for the sake of Heaven it was a mistake. This is my explanation and I think it is very correct.

Rav Tzadok(Tzedkas HaTzadik 43): There are times when a person is presented with such a great test that it is impossible that he should not sin. This is described in Berachos (32a): “How could the son not sin?” This is considered an overwhelming force and the Torah says he is exempt. Also there are times when the yetzer harah seduces with such overwhelming force that it can’t be defeated. This is also described as beyond free‑will (onas). If G‑d twists a person’s heart so that he sins - that is not considered a sin at all since it was G‑d’s will. Look at what it says in Kesubos (51b) in reference to a woman being raped and she protests strongly but at the end she says that the experience was so pleasurable she would have even paid for it. Nonetheless the gemora says she is still permitted to her husband because her lust was aroused so strongly she had no free will. She is not punished even though it is prohibited – because she was forced. However a person cannot testify on himself that he didn’t have free‑will. That is because it is still possible that he did have the power to control his desires. I heard this in regard to the incident with Zimri who erred in this matter.
