Genesis 19:30 says, And Lot went up out of Zoar, and dwelt in the mountain, and his two daughters with him; for he feared to dwell in Zoar: and he dwelt in a cave, he and his two daughters.  Lot and his two daughters lived in a cave because he was afraid to live in the city of Zoar.  He evidently no longer had to worry about any great wealth. We never read anything about Lot following God, but he always seemed to do what was best for himself.  Verse thirty-one states, And the firstborn said unto the younger, Our father is old, and there is not a man in the earth to come in unto us after the manner of all the earth:  We are not told how old the daughters were, but the oldest talked with the youngest about their father's age and the fact that there were no men around for them to start a family with.  This would have been a great concern in that time, but they must have forgotten about their great-uncle Abraham and more importantly about God.  Verse thirty-two declares, Come, let us make our father drink wine, and we will lie with him, that we may preserve seed of our father.  The oldest daughter devised a plan for them.  They would get Lot drunk and have sex with him so that they might each have a child.  As with most plans made without God's guidance, this one was very wrong.  Verse thirty-three states, And they made their father drink wine that night: and the firstborn went in, and lay with her father; and he perceived not when she lay down, nor when she arose.  Lot got very drunk that night.  It says that they got him drunk, but unless they were pouring alcohol down his throat without his consent, then I believe it is more accurate to say that Lot got drunk.  The oldest daughter went in and had intercourse with her father.  We are told that Lot did not remember this, but that does not make him blameless.  He should have been concerned about the welfare of his daughters instead of hiding in a cave getting so drunk he couldn't remember what he did.  We cannot blame our sins on others, even if we are so drunk we don't remember them.  In the first place, we shouldn't be that drunk to start with, and we should never try to hide away and ignore our responsibilities.  Verse thirty-four adds, And it came to pass on the morrow, that the firstborn said unto the younger, Behold, I lay yesternight with my father: let us make him drink wine this night also; and go thou in, and lie with him, that we may preserve seed of our father.  The older daughter told the younger daughter the next day that it was the youngest turn that night and that they would do the same thing again, only with the youngest taking the place of the oldest.  Even though the plan was not hers, the youngest was just as guilty as the oldest.  Again, we cannot blame our sins on someone else, even if we just go along with their plan.  Verse thirty-five states, And they made their father drink wine that night also: and the younger arose, and lay with him; and he perceived not when she lay down, nor when she arose.  They carried out their plan that night.  Verse thirty-six declares, Thus were both the daughters of Lot with child by their father.  Their plan was successful.  Just because our plans may be sinful doesn't mean that they won't succeed, and just because they succeed doesn't mean that they are God's plan.  Verse thirty-seven adds, And the firstborn bare a son, and called his name Moab: the same is the father of the Moabites unto this day.  The child of the first daughter was named Moab, and he became the father of the Moabites.  Verse thirty-eight concludes, And the younger, she also bare a son, and called his name Benammi: the same is the father of the children of Ammon unto this day.  The child of the second daughter was named Benammi, and he became the father of the Ammonites.  Even though they were successful in the plot, this was certainly never God's plan.
