You don't see Old Testament pointers to the rapture as much. I like this teaching as to the character and mercy of our unchanging God, boggles the mind how people believe the Lord, who would spare an entire city if ten righteous people could be found, and did spare Lot and some of his, that this same God is somehow going to engage in wrath against His spotless, forgiven bride. He would somehow spare Sodom for ten, but not millions of His own children, those His very children in Christ, declared wholly blameless and uncondemned?
Genesis 18:21 I will go down now, and see whether they have done altogether according to the cry of it, which is come unto me; and if not, I will know. 22 And the men turned their faces from thence, and went toward Sodom: but Abraham stood yet before the LORD. 23 And Abraham drew near, and said, Wilt thou also destroy the righteous with the wicked? 24 Peradventure there be fifty righteous within the city: wilt thou also destroy and not spare the place for the fifty righteous that are therein? 25 That be far from thee to do after this manner, to slay the righteous with the wicked: and that the righteous should be as the wicked, that be far from thee: Shall not the Judge of all the earth do right? 26 And the LORD said, If I find in Sodom fifty righteous within the city, then I will spare all the place for their sakes. 27 And Abraham answered and said, Behold now, I have taken upon me to speak unto the Lord, which am but dust and ashes: 28 Peradventure there shall lack five of the fifty righteous: wilt thou destroy all the city for lack of five? And he said, If I find there forty and five, I will not destroy it. 29 And he spake unto him yet again, and said, Peradventure there shall be forty found there. And he said, I will not do it for forty's sake. 30 And he said unto him, Oh let not the Lord be angry, and I will speak: Peradventure there shall thirty be found there. And he said, I will not do it, if I find thirty there. 31 And he said, Behold now, I have taken upon me to speak unto the Lord: Peradventure there shall be twenty found there. And he said, I will not destroy it for twenty's sake. 32 And he said, Oh let not the Lord be angry, and I will speak yet but this once: Peradventure ten shall be found there. And he said, I will not destroy it for ten's sake. 33 And the LORD went his way, as soon as he had left communing with Abraham: and Abraham returned unto his place.
Add to that the Lord spared Noah and family, and the New Testament teaching of the Lord Jesus clear the end times would be just as those times of Noah and Lot.
1 Thessalonians 5:9 For God hath not appointed us to wrath, but to obtain salvation by our Lord Jesus Christ.
Revelation 3:10 Because thou hast kept the word of my patience, I also will keep thee from the hour of temptation, which shall come upon all the world, to try them that dwell upon the earth.
Thought to add something of this beautiful passage in Genesis, that is how endearing both Abraham and the Lord are, Abraham so lovingly trying to intercede and, unfortunately, way out of his depth and groping in the dark, probably not the city guy, like Lot, and unaware how bad things were, asking the Lord not to get angry at him bargaining with the God of the universe, a marathon bargaining down that would surely irritate any merchant. But we have the Lord, as patient and merciful as could be, not getting angry with Abraham, as Abraham feared He surely must be getting, rather they get down to ten, and the Lord simply goes His way at the end of that business, showing all patience and willingness to oblige, and not one word of rebuke for Abraham. It's just an account I find a thing of beauty, that speaks to our Lord that listens and cares.
