Genesis 19:23 The sun had risen on the earth when Lot came to Zoar. Then the Lord rained on Sodom and Gomorrah sulfur and fire from the Lord out of heaven. And he overthrew those cities, and all the valley, and all the inhabitants of the cities, and what grew on the ground. But Lot’s wife, behind him, looked back, and she became a pillar of salt. And Abraham went early in the morning to the place where he had stood before the Lord. And he looked down toward Sodom and Gomorrah and toward all the land of the valley, and he looked and, behold, the smoke of the land went up like the smoke of a furnace. So it was that, when God destroyed the cities of the valley, God remembered Abraham and sent Lot out of the midst of the overthrow when he overthrew the cities in which Lot had lived.
Luke 17:28 Likewise, just as it was in the days of Lot—they were eating and drinking, buying and selling, planting and building, but on the day when Lot went out from Sodom, fire and sulfur rained from heaven and destroyed them all— so will it be on the day when the Son of Man is revealed. On that day, let the one who is on the housetop, with his goods in the house, not come down to take them away, and likewise let the one who is in the field not turn back. Remember Lot’s wife. Whoever seeks to preserve his life will lose it, but whoever loses his life will keep it.
1 Corinthians 10:6-12 Now these things took place as examples for us, that we might not desire evil as they did. Do not be idolaters as some of them were; as it is written, “The people sat down to eat and drink and rose up to play.” We must not indulge in sexual immorality as some of them did, and twenty-three thousand fell in a single day. We must not put Christ to the test, as some of them did and were destroyed by serpents, nor grumble, as some of them did and were destroyed by the Destroyer. Now these things happened to them as an example, but they were written down for our instruction, on whom the end of the ages has come. Therefore let anyone who thinks that he stands take heed lest he fall.
Hebrews 10:38-39 but my righteous one shall live by faith, and if he shrinks back, my soul has no pleasure in him.” But we are not of those who shrink back and are destroyed, but of those who have faith and preserve their souls.
2 Peter 2:18-22 For, speaking loud boasts of folly, they entice by sensual passions of the flesh those who are barely escaping from those who live in error. They promise them freedom, but they themselves are slaves of corruption. For whatever overcomes a person, to that he is enslaved. For if, after they have escaped the defilements of the world through the knowledge of our Lord and Savior Jesus Christ, they are again entangled in them and overcome, the last state has become worse for them than the first. For it would have been better for them never to have known the way of righteousness than after knowing it to turn back from the holy commandment delivered to them. What the true proverb says has happened to them: “The dog returns to its own vomit, and the sow, after washing herself, returns to wallow in the mire.”
Lot’s wife looked back which appears to be for a longing of the way things were. Living there was a life of what was recorded in Ezekiel 49 “Behold, this was the guilt of your sister Sodom: she and her daughters had pride, excess of food, and prosperous ease, but did not aid the poor and needy.” Change from this life caused her to turn back with a longing concern for what once was.
What keeps us from turning back or falling back into that which does not honor God? Is it not by the simple fact that through complacent neglect of His word we are deceived and diluted, by the way of the world, into thinking that which is common and natural and lawful to the culture is somehow ok for us? Oh, that our heart, mind and soul would thirst for understanding and knowledge of Him and His word. Oh that our passion was not for this world but rather to serve, honor, glorify, follow and obey Him who is worthy.
Matthew Henry comments “All the people of Sodom were very wicked and vile. Care was therefore taken for saving Lot and his family. Lot lingered; he trifled. Thus many who are under convictions about their spiritual state, and the necessity of a change, defer that needful work. The salvation of the most righteous men is of God’s mercy, not by their own merit. We are saved by grace. God’s power also must be acknowledged in bringing souls out of a sinful state If God had not been merciful to us, our lingering had been our ruin. Lot must flee for his life. He must not hanker after Sodom. Such commands as these are given to those who, through grace, are delivered out of a sinful state and condition. Return not to sin and Satan. Rest not in self and the world. Reach toward Christ and heaven, for that is escaping to the mountain, short of which we must not stop. Concerning this destruction, observe that it is a revelation of the wrath of God against sin and sinners of all ages. Let us learn from hence the evil of sin, and its hurtful nature; it leads to ruin.”
