"And Lot went out, and spake unto his sons in law, which married his daughters, and said, Up, get you out of this place; for the LORD will destroy this city. But he seemed as one that mocked unto his sons in law.
And when the morning arose, then the angels hastened Lot, saying, Arise, take thy wife, and thy two daughters, which are here; lest thou be consumed in the iniquity of the city.
And while he lingered, the men laid hold upon his hand, and upon the hand of his wife, and upon the hand of his two daughters; the LORD being merciful unto him: and they brought him forth, and set him without the city."

                            -Genesis 19:14-16

I recently finished reading all the way through the Bible, and have just started again with the book of Genesis. With that said, it has obviously been a long time since I read about the destruction of Sodom and Gamorrah, and I noticed something brand new yesterday as I was reading this passage of Scripture: the words, "while he lingered." In verse 14, Lot was doing everything he possibly could to save his sons-in-law, yet in verse 16 the angels of God had to pretty much drag him away from his home so that he himself would be saved.

If you read this entire chapter in Genesis, and then turn over to the New Testament and read about the second coming of Christ, you will doubtless see many parallels between the two. God destroyed Sodom and Gamorrah, but first saved Lot, just like He will destroy this earth after first delivering His saints from the wrath to come (I Thessalonians 1:10; II Peter 3:10, 12). However, just as Lot "lingered", I'm afraid that many saints of God today are doing the same. Jesus has told us that we must always be ready for Him to return at any time (Mark 13:32-37), and yet many of us are still unprepared.

"And while they went to buy, the bridegroom came; and they that were ready went in with him to the marriage: and the door was shut.
Afterward came also the other virgins, saying, Lord, Lord, open to us.
But he answered and said, Verily I say unto you, I know you not."

                            -Matthew 25:10-12

When Christ comes, we will either be prepared or unprepared. If we are unprepared, there will be no more second chances, no more do-overs, no more restarts. We've got to make ourselves ready today.
