Musar к Дварим 7:15

The eighteenth thing one must remember is the kindness of God, Who saves him from the afflictions of the world. For he sees so many people dying in great pain from hunger, from thirst, from poison, from leprosy, from the sword, from drowning, and from fire, and he knows in his heart that he deserves to be visited with all sorts of afflictions because of many transgressions which he has committed, and that he has not guarded that which God has placed in his care. And even though he is a completely wicked person, God has had pity upon him and saved him from all these afflictions. He should know how fitting it is for him to be submissive before his Creator and ask Him to guard him against all the distress that takes place in the world. As it is said, "If thou wilt diligently hearken to the voice of the Lord thy God… I will put none of the diseases upon thee, which I have put upon the Egyptians; for I am the Lord that healeth thee" (Ex. 15:26). And it said, "And the Lord will take away from thee all sickness; and He will put none of the evil diseases of Egypt, which thou knowest, upon thee" (Deut. 7:15). And our Rabbis, of blessed memory, said, "It is not the lizard that slays, but it is sin that slays" (Berakoth 33a).
