This passage begins with the warning that "The burning wrath of a great multitude is kindled over you. There will be a great uprising against those who fear the Lord." and continues, "They shall be like maniacs, sparing no one, but blundering and destroying."
"The Lord says, 'Listen, my elect ones, the days of tribulation are at hand, but I will deliver you. Do not let your iniquities prevail over you."
The New Interpreter's Study Bible commentary points out that the description of destruction may well reflect real events in the 3rd century CE. Even so, we can reflect on the inevitable consequences of our sinning and the opportunity to be forgiven.
