The story of Noah's flood and the details that are often spewed out from many people (often times, Christians included) are seldom in line with the details the Bible provides. Many people have dismissed the account of the flood as a story equal to a fairy tale because they can't seem to rationalize the account in their minds. Unfortunately, the reason for this is because many people tell the story incorrectly.
In Genesis 6:9-22 God calls out to Noah to warn him about the flood. Though God looked down at the earth and saw only violence and corruption, Noah stood out amongst his contemporaries as a righteous man since the Bible describes that, like Enoch, Noah walked with the Lord. Though the world was living wicked lives, rebelling against God, seeking to remove Him from life, Noah lived contrary to the ways of the world. Noah found it best to seek God instead of following the ways of the people around him. Therefore the Bible explains that God saw favor in Noah, as well as his family. There is an interesting truth that the scriptures present in this regard. Genesis 6:9-22 explains that God desired to save Noah. While it is a normal habit of God to always save a remnant of righteousness in the midst of His judgment, the details of how God would save Noah's family are interesting. The scriptures clearly explain that Noah was righteous, but fail to say anything about his wife or his sons Shem, Ham, and Japheth. Hence, it is implied that the righteousness of Noah extended throughout his family so that God saw them as righteous as well. In this way, the righteousness of one man is able to extend out to the righteousness of many, just like Christ!
In Genesis 6:9-22 God provides plenty of details regarding His coming judgment and the manner in which Noah would be saved. People often say that God works in mysterious ways. The Bible does not support such a belief. The Bible shows that God clearly communicates to His people in order to inform them of His work and then involved them in His work. God was clear to explain that He was going to destroy all people, and all things that had "life blood" in them (which is defined in Leviticus 17). The Bible teaches that the wages of sin is death. While some people encourage sinful activity, often saying things like, "If it doesn't hurt anyone else then its okay," the Bible proves this thought process to be severely flawed. Genesis 6:9-22 reveals that sin infects all of God's creation and requires cleansing through His judgment. There is no such sin that only affects the person committing it.
Understanding this truth, God spared the few that were righteous - 8 people. God clearly communicated His provision for salvation. There was no mystery that Noah had to solve. There was no higher state of consciousnesses that Noah had to achieve. There was no ritual process or rite of passage that Noah had to endure. God said the world would be judged, but in order to be saved from the coming flood, Noah had to build a barge. In order to Noah to be saved, he needed faith. Noah needed to trust in God's judgment and that it was real. He had to admit that the world was broken according to God's standards, and that God would fix that problem. Noah had to trust that God's wrath would come upon the whole world, not thinking that he could flee God's wrath in some other place. Though Noah had never seen a flood, he had to trust that it would be as destructive and real as God said. Though Noah had never seen an ark as he was commanded to build, he had to trust that he and his family would be safe if they just did what God said. Simply put, Noah had to trust in the Word of God to be true.
Genesis 6:9-22 also provides details as to how God would spare life on this planet in the midst of His wrath. The scriptures detail the dimension of the ark that Noah was to build in 120 years. The length of the ark was to be about 450 feet long. This is about twice the size of a Boeing 747 airplane, about 2/3 the size of the Titanic, and about the size of one and a half football fields! The width of the ark was to be about 75 feet, which is about a quarter of a football filed. God stated that the ark was to be about 45 feet high, which is about the height of a modern day 4-story building (though the ark was to have only 3 levels). Examining these dimensions, the ark resembled a barge more than a boat. The Lord instructed Noah to place a roof over the ark, a door and a window. Noah was to follow these instructions and upon following these instructions, Noah and his family would be saved from God's judgment.
Genesis 6:9-22 also explains the work that God would do in order to keep life going on the planet. While many people think that it was Noah's job to bring all of the animals onto the ark, the Bible does not say that. The scriptures clearly state that God would bring the animals to Noah. Many people question how Noah would have been able to get all the animals on the ark. The truth is, the scriptures never attribute that responsibility to Noah. The sovereign God who controls all things would be responsible for bringing the animals into the ark.
Lastly, Genesis 6:9-22 explains the issue about the animals. Many people discredit the testimony of God's judgment against sin by the flood because they cannot imagine how an ark of this size could hold 2 of every animal. The misconception is that God placed 2 of every animal in the ark. The scriptures do not say that God placed two of every animal in the ark. This scriptures say that God placed two of every "kind" of animal on the ark. Genesis 6:9-22 is even detailed to explain what God meant by "kind." The scriptures state that two of every "kind" of bird were to be placed on the ark. The scriptures state that two of every "kind" of livestock were to be placed upon the ark. The scriptures state that two of every "kind" of animal that crawls on the ground was to be placed on the ark. God saved the animals categorically, not individually. Since God created the animals with extensive DNA information containing all data to provide an abundance of variation through breeding, He didn't need to save every animal. The Bible shows that God only said He would save every "kind" of animal. God would save the K9 "kind" and from that would come all of the different species of dogs (poodles, retrievers, wolves, etc). Understanding this truth, one discovers that the ark does not need to house millions of animals, only thousands, which a vessel of this size was well equipped to do. Some object to the idea of the flood because it is difficult to to imagine how a vessel of this size could house a full grown dinosaur such as seen in museums. This is why God would give Noah younger "kinds" that are smaller in size to ensure that they fit.
The truth of the matter is that many of the objections people have regarding the testimony of God's judgment in the flood stems from ignorance. People just don't know what the Bible says - believer and non-believer alike. Nevertheless, God's Word is truth. God clearly communicated to those He considered to be righteous that judgment was coming. God is a just judge and will not let sin go unpunished. The flood is evidence of God's judgment and that sin has consequence. However, the continued existence of humanity is evidence of God's grace. Though God would have been fair to extinguish all living things, including Noah and his family, He decided to show grace and spare Noah and his family, leaving a remnant of righteousness on the earth. The scriptures reveal that Noah's righteousness was not on account of what he knew, what he did, or who he was associated with. Instead, the Bible shows that Noah was saved from God's wrath because Noah trusted in the Word of God. Since God does not change, neither does His provision for salvation. Those who walk with God in faith, with Jesus Christ as the object of faith, will be saved. Those who choose to do otherwise, will not be saved. The Bible is clear to explain these truths. As people, we simply need to decide on whether we believe its claims to be true.
