Blessing/Promise of the Righteous

From: “In the Haredi Rooms:
The tragedy that befell the Steyer family of Beit Shemesh when the head of the family, the young Rabbi Yisrael, z”l, one of the leaders of Gur Hasidism in the city and one of the greatest students of its sages, was taken from them, who passed away after a serious illness that had taken hold of his body, led the family to ask why the blessing of the righteous who blessed the sick man that he would be healed, and their promise that he would recover, were not fulfilled.
The one who answered the difficult question is the eminent Hasidic Rabbi Yitzhak David Alter, son of the Rebbe of Gur, ztzu”l, and head of the kollel for the teaching of Gur Hasidim in Bnei Brak. In a five-paragraph letter, published in the first issue of Behadrei Haredim, he explains the matter in a moving manner that strengthens faith in the righteous and in the Creator of the world.
‘Behaderi’ brings his letter, which was sent to the family members, when, in a temporary order to his son Rabbi Yisrael Mordechai of Beit Shemesh, he writes that the page can be shown to anyone who needs it. Thus the Rabbi writes:
“A. The late Rabbi of ‘Beit Israel’ was visiting the sick with the late Rabbi Leibel Weissbaum about two weeks before his passing and told him, ‘I promise you that you will come to me for more trips.’ When he left, he turned to Rabbi Kornik, the late Rabbi, and said to him, ‘I know he is about to leave, but what are we not doing to strengthen a Jew?'”
“And so it was with my father, the teacher of ‘Peni Menachem,’ who said to a Jew on the phone on the eve of Shavuot, ‘You will catch me with the words that I promised you to have joy with your grandson,’ and when he finished the conversation, he told me what I would not do to strengthen him, even though I knew his days were numbered.”
“B. Every person will eventually die, and according to doctors, many times he does not function for more than a few months or days, and through the blessing of the righteous for complete recovery, he is granted further longevity and sometimes even the right to marry the descendants of his loins, even though he eventually dies from the same disease.”
“3. Who is greater to us than Moses our Lord, may God have mercy on him, who prayed 156 prayers and was of no avail? Yes, the blessing of the righteous is like a prayer and sometimes it is completely beneficial, sometimes it is only half-effective, and sometimes it is not even that.”
“D. Sometimes it is like the statement of the prophet Elisha, ‘And the Lord has taken away from me,’ when after the Shunammite’s son died and she came to him, he asked her about the child’s well-being, and he studied with wisdom what he had written in it.”
“E. The blessing of a righteous person is like a blessing from God, and there is not always a means of receiving it, and sometimes the recipient’s merit is still not enough to receive the blessing.”
