DEUT366 One is required to contemplate and realize that the tribulation that has befallen him and the suffering that has beset him are not commensurate to the gravity of his transgression in the amount of his sins. Rather, Hashem chastises him in the manner of a father his son, out of His compassion for him [Vayera 19:16], as the pasuk says [this verse], "You shall realize in your heart that just as a man chastises his son, so Hashem, you God, chastises you." Our Sages, z"l, commented on this (Yalkut Shemos 303): "Your heart realizes [from] the actions you have committed and the chastisement I have a brought upon you, that I have not chastised you commensurate to your deeds. The pesukim further say (Iyov 11:6), "Know, that God exacts from you [less] than your transgressions [deserve]"; and (Ezra 9:13), "For you, our God, withheld [Your punishment] to less than our transgressions [deserve]."
