God’s Judgment Upon The Wicked Is The Salvation Of His People

2 Peter 2:7-9 English Standard Version (ESV)

“(A)nd if he rescued righteous Lot, greatly distressed by the sensual conduct of the wicked (for as that righteous man lived among them day after day, he was tormenting his righteous soul over their lawless deeds that he saw and heard); then the Lord knows how to rescue the godly from trials, and to keep the unrighteous under punishment until the day of judgment, and especially those who indulge in the lust of defiling passion and despise authority.” 

But without this passage most would assume Lot was unsaved. As in His destruction of Sodom, in every Day of the Lord, when He brings judgment on earth, God is also saving his righteous people from the wicked.
