In Gen. 6:11-12 “The earth also was corrupt before God, and the earth was filled with violence. So God looked upon the earth, and indeed it was corrupt; for all flesh had corrupted their way on the earth.”
1.Today’s Day is like Noah's day: Many people are taking pleasure in rebellion and unrighteousness. Violence has filled the earth. Everywhere we see the violence, all manner of unrighteousness, sins, immorality, corruption, sinful nation of idolaters, child murderers, drunkards, gamblers, pornographers, haters, backstabbers, liars, adulterers, sexual sinners, murders, lifestyles that are abominations before God. The Lord Jesus indicates that the world which exists before His return will be given over to pleasure-seeking, immorality, perversion, idleness, and a rejection of the things of God.( Psalm 9:17)
2. Judgment is coming as it was in the days of Noah:
Luke 17:26-33 Jesus says, "When the Son of Man returns, the world will be like the people were in Noah's day. In those days before the flood, the people enjoyed Banquets and Parties and Weddings right up to the time Noah entered his boat and the flood came to destroy them all. "And the world will be as it was in the days of Lot. People went about their Daily Business, Eating and Drinking, Buying and Selling, Farming and Building, until the morning Lot left Sodom. Then Fire and Burning Sulfur rained down from heaven and destroyed them all. Yes, it will be 'Business As Usual' right up to the hour when the Son of Man returns…Whoever clings to this life will lose it, and whoever loses this life will save it.”
Matt 24:37-39 Jesus says, “When the Son of Man (Jesus) returns, it will be like it was in Noah’s day. In those days before the flood, the people were enjoying banquets and parties and weddings right up to the time Noah entered his boat. People didn’t realize what was going to happen until the flood came and swept them all away. That is the way it will be when the Son of Man comes.”
2 Peter 3:3-7 First of all, you must understand that in the last days scoffers will come, scoffing and following their own evil desires. 4They will say, "Where is this 'coming' he promised? Ever since our fathers died, everything goes on as it has since the beginning of creation." 5But they deliberately forget that long ago by God's word the heavens existed and the earth was formed out of water and by water. 6By these waters also the world of that time was deluged and destroyed. 7By the same word the present heavens and earth are reserved for fire, being kept for the day of judgment and destruction of ungodly men.
2 Peter 2:6-9 6if he condemned the cities of Sodom and Gomorrah by burning them to ashes, and made them an example of what is going to happen to the ungodly; 7and if he rescued Lot, a righteous man, who was distressed by the filthy lives of lawless men 8(for that righteous man, living among them day after day, was tormented in his righteous soul by the lawless deeds he saw and heard)if this is so, then the Lord knows how to rescue godly men from trials and to hold the unrighteous for the day of judgment, while continuing their punishment.
2Timothy 3:1-7 This know also, that in the last days perilous times shall come. For men shall be lovers of their own selves, covetous, boasters, proud, blasphemers, disobedient to parents, unthankful, unholy. Without natural affection, trucebreakers, false accusers, incontinent, fierce, despisers of those that are good. Traitors, heady, high-minded, lovers of pleasures more than lovers of God. Having a form of godliness, but denying the power thereof: from such turn away.
Zephaniah 1:14-18 Neither their silver nor their gold will be able to save them, on the day of the LORD's wrath. In the fire of his jealousy the whole world will be consumed, for he will make a sudden end of all who live in the earth."
1 Thessalonians 5:2 -3For you know very well that the day of the Lord will come like a thief in the night. While people are saying, "Peace and safety," destruction will come on them suddenly, as labor pains on a pregnant woman, and they will not escape.
Mark 13:34-37:34It's like a man going away: He leaves his house and puts his servants in charge, each with his assigned task, and tells the one at the door to keep watch.
35"Therefore keep watch because you do not know when the owner of the house will come back—whether in the evening, or at midnight, or when the rooster crows, or at dawn. 36If he comes suddenly, do not let him find you sleeping. 37What I say to you, I say to everyone: 'Watch!' "
3. Men did not repent during Noahs days:
During Noah days, the people had no time for God, no thoughts of God, no time for repentance they pursued all unrighteousness and rebelled against God and his commandments. They refused to believe the gospel message preached by Noah. They were unconvinced, unpardoned, unconverted and unsaved. The lifestyle in Noah’s day was remarkably similar to that which is found on the earth today. Man today, for all his culture, education and progress, is no different than in the days of Noah. Just as in Noah’s day, man today is busy with life, eating and drinking, marrying and giving in marriage, buying and selling, and so on. These are normal human activities that are not wrong in themselves. The problem is, man is too busy for God. Man is ignoring God’s warning of impending judgment and will not accept God’s offer of a free salvation declared in the gospel message. Also, we need only to read or hear the daily news reports, regarding conditions in the world, to realize that corruption and violence fill the earth today more than ever before. Time has not changed or improved the sinful condition of man. All of those people in Christ's presence that did not repent at that time did perish without receiving salvation.( Luke 13: 4-5)
Revelation 9:18-21 : third of mankind was killed by the three plagues of fire, smoke and sulfur that came out of their mouths. The power of the horses was in their mouths and in their tails; for their tails were like snakes, having heads with which they inflict injury. The rest of mankind that were not killed by these plagues still did not repent of the work of their hands; they did not stop worshiping demons, and idols of gold, silver, bronze, stone and wood—idols that cannot see or hear or walk. Nor did they repent of their murders, their magic arts, their sexual immorality or their thefts.
Revelation 16:9 :9They were seared by the intense heat and they cursed the name of God, who had control over these plagues, but they refused to repent and glorify him
