The biblical account of Noah begins in Genesis 6. Approximately 1,600 years had passed since the creation of male and female (them is plural) described in Genesis 1:26-27 (KJV). The forming of Adam and Eve occurs in Genesis 2 starting with verse 5 forward to at least verse 22; some teach that they (Adam and Eve) were created in chapter 1 of Genesis. Where does their forming occur in God’s word? Chapter 2 of Genesis; God doesn’t make mistakes. Also, notice that their forming is singular; one man and one woman. As the earth’s population exploded in number, it also exploded with evil. Long forgotten was the righteous sacrifice of Abel (Genesis 4:4) as “the Lord saw that the wickedness of man was great in the earth, and that every intention of the thoughts of his heart was only evil continually” (Genesis 6:5). Verses 11 and 12 say, “The earth also was corrupt before God, and the earth was filled with violence. And God looked upon the earth, and, behold, it was corrupt; for all flesh had corrupted his way upon the earth. However, “But Noah found grace in the eyes of the LORD.” (verse 8).
When Jesus described the events that will surround His second coming, He said, “And as it was in the days of Noe, so shall it be also in the days of the Son of man. They did eat, they drank, they married wives, they were given in marriage, until the day that Noe entered into the ark, and the flood came, and destroyed them all.” (Luke 17:26–27). Jesus was pointing out that, although the people of Noah’s day were totally depraved, they were not the least bit concerned about it. Sound familiar? They were carrying on the events of their lives without a single thought of the judgment of God; many deny He even exists. Noah is described as a “preacher of righteousness” (2 Peter 2:5), meaning he had spent years warning his friends and neighbors what the Holy God was about to do. No one listened.
The depravity and ungodly lifestyles of the entire world at that time were enough to cause the Lord to “regret that He had made man” (Genesis 6:6). Many scholars believe that part of the need to destroy every human being except Noah and his family was the sin mentioned in Genesis 6:1-4, when “the Nephilim were on the earth in those days, and also afterward, when the sons of God came in to the daughters of men, and they bore children to them.” As evil reproduced and overtook the world, the most merciful act God could perform was to start over.
It is interesting that God allowed Noah nearly one hundred years to complete the building of the ark. Through all that time, God patiently waited (1 Peter 3:20). Scripture seems to imply that Noah preached to the people of that time about what was coming (Hebrews 11:7). They did not believe Noah and were content with their wickedness and idolatry. Their hearts were hard and their ears dull. No one repented, and no one cared to seek God; again, sounds extremely familiar.
Jesus said that the world will be much the same before He returns to set up His earthly kingdom (Matthew 25:31-33). He warned us to “be ready, because the Son of Man will come at an hour when you do not expect him.” 2 Timothy 3:1-5gives us a clear picture of the state of the world before Jesus comes and most likely also describes the world in the days of Noah. That verse says, “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, truce breakers, false accusers, incontinent, fierce, despisers of those that are good, Traitors, heady, highminded, lovers of pleasures more than lovers of God; Having a form of godliness, but denying the power thereof: from such turn away.” It is becoming increasingly obvious that, to understand what the world was like in the days of Noah, we only need to study our Bibles and watch the evening news each day in 2022 and beyond.
