Book of Genesis - Original Sin
The Book of Genesis introduces the reality of "Original Sin." Many people have a problem with this concept -- the idea that Adam introduced sin into the entire world. However, it's not much different than a hereditary disease. Many family lines are plagued by the hereditary predisposition to developing certain kinds of cancers or other physical and mental diseases. Similarly, your great, great, great, great...granddaddy, Adam, contracted sin and now you've got it! Every man, woman and child is a descendant of Adam and so we all suffer from his spiritual affliction: we're all sinners. The Bible accuses us of being "lovers of pleasures more than lovers of God" (2 Timothy 3:4). If you're not sure whether you're a sinner, here's a checklist:
God has ten basic moral laws that He expects everyone to live by:
Book of Genesis - The Flood
The Book of Genesis records a worldwide deluge. Within just a few hundred years after the Fall of Man, mankind became morally bankrupt. This rampant immorality incited God's righteous indignation. "Then the LORD saw that the wickedness of man was great in the earth, and that every intent of the thoughts of his heart was only evil continually. And the LORD was sorry that He had made man on the earth, and He was grieved in His heart. So the LORD said, 'I will destroy man whom I have created from the face of the earth, both man and beast, creeping thing and birds of the air, for I am sorry that I have made them.' But Noah found grace in the eyes of the LORD" (Genesis 6:5-8). God warned the world through His prophets that He was going to judge the world with the Flood. Enoch, a prophet of God called to warn the world of the coming judgment, even prophetically named his son "Methuselah," which means "his death shall bring." Nevertheless, the world did not repent.
In addition to the Book of Genesis, nearly three hundred ancient Flood legends have survived the obscurity of time -- legends of a worldwide deluge found throughout Europe, Asia, Africa, Australia, and the Americas. These Flood legends include two of the oldest known stories to have survived the ravishment of time's passage, China's Hihking classic and Babylon's epic Gilgamesh. These Flood Legends are remarkably consistent considering the relative isolation of the cultures and the length of time that elapsed since the Flood. Of the approximately 300 ancient accounts, 95% tell of a lone flood disaster, 95% claim the Flood was global, 88% tell of a favored family of humans saved from drowning to reestablish the human race, 66% say the family was forewarned of the coming cataclysm, 66% blame the wickedness of mankind for the deluge, and 70% record a boat as being the means by which the chosen family (and animals) survived the Flood.
The Book of Genesis declares that the eight humans who disembarked from Noah's Ark after the flood waters receded were all that remained of the human race. These eight were Noah, his wife, their three sons and their sons' three wives. Thus, every human is a direct descendent of this small remnant.
