God can selectively rescue us from harm.
Exodus 12:13 (ESV)
"The blood shall be a sign for you, on the houses where you are. And when I see the blood, I will pass over you, and no plague will befall you to destroy you, when I strike the land of Egypt."
2 Peter 2:9 (ESV)
"then the Lord knows how to rescue the godly from trials, and to keep the unrighteous under punishment until the day of judgment"
I guess the bible is clear in Romans 8:20 on too much personalization (i.e. particular punishment or result of a particular sin) of sufferings, as he put the whole creation under the path of destruction(futility) since the time of the original fall of man.
