Today there are three chapters.
John 8 begins with the sinful woman about to be stoned. Jesus last words to her is “Go and sin no more”. Jesus does not condemn for the past but looks to the future. The he gets into an argument with the religious powers to be about his and their ancestry. They claimed to be descendants of Abraham, and they questioned the legitimacy of Jesus. Jesus answered “Before Abraham, I am”. This was blasphemy, unless it is true.
Which brings us to Genesis 18 with Abraham still waiting for his offspring. He is visited by three angels that promise him he will have a son within a year. God confirms this promise, but is also proclaiming the destruction of Sodom and Gomorrah. Abraham tries to bargain with God, at no avail.
So in Genesis 19 Sodom and Gomorrah are destroyed. There is ample evidence this is a historical true event, so the Bible is verified true even here. God provides for Lot, his wife and two daughters to escape.They do, but Lot’s wife looks back towards the city and is no more. Then comes a story about Lot and his two daughters, and all I can say about that is that it is not good to take matters in our own hand rather than listen to God and let Him guide.
