Luk 17:24 For as the lightning flashes and lights up the sky from one side to the other, so will the Son of Man be in his day.
Luk 17:25 But first he must suffer many things and be rejected by this generation.
Luk 17:26 Just as it was in the days of Noah, so will it be in the days of the Son of Man.
Luk 17:27 They were eating and drinking and marrying and being given in marriage, until the day when Noah entered the ark, and the flood came and destroyed them all.
We have this promise in genesis:-
Gen 8:20 Then Noah built an altar to the LORD and took some of every clean animal and some of every clean bird and offered burnt offerings on the altar.
Gen 8:21 And when the LORD smelled the pleasing aroma, the LORD said in his heart, "I will never again curse the ground because of man, for the intention of man's heart is evil from his youth. Neither will I ever again strike down every living creature as I have done.
Gen 8:22 While the earth remains, seedtime and harvest, cold and heat, summer and winter, day and night, shall not cease."
So we know that the worsening weather conditions that we are beginning to experience are not the instruments of the end of the age. However, we ought to ponder this - that from the time of the flood abating, the polar ice-caps came into existence and the climate change was immense compared to pre-flood conditions. We have had around 5,000 years of these conditions now. Now, however, things are changing and no-one has a thorough explanation for it all. Israel is back in the Land and many alive today are probably going to witness the return of the Lord. With unprecedented communication technology, the preaching of the gospel to the entire world prior to the return of the King, the Lord, Jesus Christ, is not a problem.
