I know a Chashuva Yid who was very sick, Rachana Litzlan. After a long time he had a Refua... but other inconveniences took place in his life. He told me that he truly doesn’t care which way things turn in his life, since: כָּל מַאי דְ עָּבֵיד רַחְמָּנָּא לְטַב עָּבֵיד whatever Hashem does, is surely best! I’ve known this person for a long time, and indeed, he has a certain Menucha and Simcha about him.
The Shomer Emunim says that being like this is the highest Madrega, and such a person is always very strong and almost infallible. The Chovos Halvavos at the end of Shaar HaBitachon speaks about a Tzaddik who said מֵעוֹלָּם לֹא הִשְכַמְתִי לְדָּבָּר וְהִתְאַוֵיתִי לְזוּלָּתוֹ “I never woke up to one situation and desired a different situation.”
