Theologically I think the Flood of Noah’s day is a sign pointing to a number of aspects of modern day faith. In no particular order;
1) A global Day of Judgement is coming just like the Flood but not with water this time. 2 Peter 3:6-7.
2) There was only one way to be saved from God’s judgement and that was by going through the door of the Ark. There is also only one way to enter into God’s Kingdom and that is through ‘The Door’ Jesus. Luke 13:22-25, Luke 11:9, Matthew 7:8.
3) The door of the Ark was open for seven days with all on board to allow many to enter, but only the seven with Noah entered and then it was too late to enter because God had shut the door. Genesis 7:4, 10, 16b. Jesus has also opened the door for all to enter before the Day of Judgement, but he doesn’t force people on board. The seven days are a bit like the life of a person, with the end of the seventh day being the end of the person’s earthly life. Each of us are warned to get on board with Jesus in this life before we are judged, because after the seventh day judgement is upon us and it is too late to get on board as the door is shut. Acts 17:30-31, Luke 13:25.
4) The Ark is not a boat but a box. This demonstrated in the building instructions in that there is no rudder, no sail, no way to steer the vessel in any way. The people on board had to totally rely on the Lord to guide them to safety. This idea was repeated in the wilderness with the Lord leading the Hebrews by fire at night and by cloud in the day. When we trust in Jesus we must let Him set the direction of our life relying totally on His word as Noah and Moses did. Sometimes what Jesus tells us doesn’t make sense like the beatitudes seem to tell us to do the opposite of what ever comes naturally, but Jesus knows what is best because He made us.
5) There is also no life boats on the Ark, the Ark is the life boat. We can’t get on board with Jesus and have a back up plan. We can’t trust in Jesus and rely on eating the Mass, or praying to the saints, or any good deeds we can imagine. Trusting in Jesus is the only way to salvation, if a person is still relying on those other things they are not on the Ark of salvation.
6) The forty days of rain is the first time God uses the number forty in setting up a new covenant. The idea is repeated with Moses on Mount Sinai, and with Jesus temptation in the desert.
Also apart from the theological points which there are many more than I have listed, the Flood event is one of the few events people have to test if the Bible is historically accurate and not just a made up religion. This is important if Peter is going to use the Flood event as proof of the coming judgement with fire as a reason to repent.
So if the Bible is accurate in what it says, that God will end all life on the surface of the Earth (Genesis 6:17) then there would be significant evidence for it on the earth, and the Devil will try to cover up the evidence.
In my biology degree I studied Palaeontology for two subjects. This really reaffirmed my faith in the Scriptures. For example the most common fossil in the world is the brachiopod. Which is a bivalve a bit like a Mussel but on a pedicle, this creature lived all over the world in the benthenic regions (meaning just off the shore of many islands). In a single event these creatures have reduced there number of species by 99%. The reason they died is that they were rapidly covered in sediment globally. Because Brachipods are on a pedicle (like the stork of a flower) and not free to move around they had no way to adjust to the rapid sedimentation, unlike some other bivalves that are free moving. They are also relatively delicate unlike oysters that can withstand the rigors of thrashing with waves, brachipods die when there pedicle is broken because they can no longer feed.
Also in Palaeontology there is claimed to be five major extinction events, where between 95-99% of all life is destroyed in each event. Evolution can not account for the repopulation of the Earth after each event, it does not have enough time. However if it is only one extinction event as is claimed in the Bible then the evidence matches.
The Flood event is also the only logical explanation for the Ice Age, as a large amount of water vapour needs to enter the atmosphere combined with a cooling biosphere. There is no event in Science history that sufficiently explains an Ice Age, however if the water for the Great Flood did come from the fountains of the great deep, then this implies large scale volcanic activity throwing dust into the air that reflects the Sun chilling the atmosphere, combined with the water vapour and glaciation on a large scale occurs.
Any how just some thoughts.
