From the Babylonian Talmud, Massechet Brachot page 5b

R. Hiyya b. Abba fell ill and R. Yohanan went in to visit him. He said to him: Are your sufferings welcome to you? He replied: Neither they nor their reward.  He said to him: Give me your hand. He gave him his hand and he raised him.

R. Yohanan once fell ill and R. Hanina went in to visit him. He said to him: Are your sufferings welcome to you? He replied: Neither they nor their reward. He said to him: Give me your hand. He gave him his hand and he raised him. Why could not R. Yohanan raise himself?  — They replied: The prisoner cannot free himself from jail.

R. Eleazar fell ill and R. Yohanan went in to visit him. He noticed that he was lying in a dark room and he bared his arm and light radiated from it. Thereupon he noticed that R. Eleazar was weeping, and he said to him: Why do you weep? Is it because you did not study enough Torah? Surely we learnt: The one who sacrifices much and the one who sacrifices little have the same merit, provided that the heart is directed to heaven. Is it perhaps lack of sustenance? Not everybody has the privilege to enjoy two tables. Is it perhaps because of [the lack of] children? This is the bone of my tenth son! — He replied to him: I am weeping on account of this beauty that is going to rot in the earth. He said to him: On that account you surely have a reason to weep; and they both wept. In the meanwhile he said to him: Are your sufferings welcome to you? — He replied: Neither they nor their reward. He said to him: Give me your hand, and he gave him his hand and raised him.

Interpretation:

Physical suffering is connected to emotional experiences and the will to live is important for someone who wants to improve physically. The first time Rabbi Yohanan was just interested in solving the problem. After the experience of his own illness, he became more empathetic. The second time he visited a friend, he dealt with the emotional issues, identified with the person, cried together, faced their own vulnerability and mortality, and only then presumed to raise his friend from the state of illness.
