Genesis 19:17-22 And it came to pass, when they had brought them forth abroad, that he said, Escape for thy life; look not behind thee, neither stay thou in all the plain; escape to the mountain, lest thou be consumed. And Lot said unto them, Oh, not so, my Lord: Behold now, thy servant hath found grace in thy sight, and thou hast magnified thy mercy, which thou hast shewed unto me in saving my life; and I cannot escape to the mountain, lest some evil take me, and I die: Behold now, this city is near to flee unto, and it is a little one: Oh, let me escape thither, (is it not a little one?) and my soul shall live. And he said unto him, See, I have accepted thee concerning this thing also, that I will not overthrow this city, for the which thou hast spoken. Haste thee, escape thither; for I cannot do anything till thou be come thither. Therefore the name of the city was called Zoar.
Note here that Lot believed he had found grace in God’s sight and yet begged not to obey God’s gracious gift. When told to go to the mountain Lot said no. He offered up an alternative, as if he, Lot, was holding God captive in the moment and could extract a bit more grace beyond what was spoken.
Lot’s asking was based on a false assumption, that he, Lot, had found favor in God’s eye.
Genesis 19:29 And it came to pass, when God destroyed the cities of the plain, that God remembered Abraham, and sent Lot out of the midst of the overthrow, when he overthrew the cities in the which Lot dwelt.
God saved Lot because of the love that He had for Abraham. In like kind we should keep in mind that the grace extended to us is much the same. We are the bride of Christ and that which the Son loves, the Father loves and treats graciously.
