Remember Lot's wife.
Genesis 19:17
And when they had brought them forth, they said, "Flee for your life; do not look back or stop anywhere in the valley; flee to the hills, lest you be consumed."
Genesis 19:26
But Lot's wife behind him looked back, and she became a pillar of salt.
1 Corinthians 10:6-12
6
Now these things are warnings for us, not to desire evil as they did.
7
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 dance."
8
We must not indulge in immorality as some of them did, and twenty-three thousand fell in a single day.
9
We must not put the Lord to the test, as some of them did and were destroyed by serpents;
10
nor grumble, as some of them did and were destroyed by the Destroyer.
11
Now these things happened to them as a warning, but they were written down for our instruction, upon whom the end of the ages has come.
12
Therefore let any one who thinks that he stands take heed lest he fall.
Hebrews 10:38
but my righteous one shall live by faith, and if he shrinks back, my soul has no pleasure in him."
Hebrews 10:39
But we are not of those who shrink back and are destroyed, but of those who have faith and keep their souls.
2 Peter 2:18-22
18
For, uttering loud boasts of folly, they entice with licentious passions of the flesh men who have barely escaped from those who live in error.
19
They promise them freedom, but they themselves are slaves of corruption; for whatever overcomes a man, to that he is enslaved.
20
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 overpowered, the last state has become worse for them than the first.
21
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.
22
It has happened to them according to the true proverb, The dog turns back to his own vomit, and the sow is washed only to wallow in the mire.
