I have, against my better judgment, been reading the waterfall of comments at BHT regarding whether or not we should "believe" or "believe in" Noah's Ark, and whether there's anything to be gained in playing Indiana Jones in seeking out the remains of a big wooden boat which somehow beached on a mountain top a few thousand years ago.
Let me say, first, that I unequivocally believe that God covered the Earth in water and spared one family because of His relationship with the father of that family, Noah. And let me also say that Noah was a wine-bibber, and that the first thing he did after thanking God for the promise of the rainbow was to plant a vineyard, grow some grapes, make some wine, and get drunk -- proving that Noah wasn't saved because he was inherently good, but because God is merciful. I believe it, and I really don't have any arguments to support my belief.
I also, by the way, am not looking for archeological proof or evidence. For example, I am not really interested in funding expeditions in to all the mountains of Turkey, Iran and Iraq in order to find the remnants for the big boat. And that has nothing to do with blindness of faith or intransigence of ignorance: it has to do with the reason I believe that Noah built an arkie-arkie.
My reason, for whatever you take it to mean, is Jesus Christ. See: in my view, it is historically indisputable that Jesus Christ died, was buried, and then did something as amazing as building a big boat and putting 2 of every animal onto that boat, and then living on that boat for about a year until the water went down. Jesus Christ, in an event as real as the failed missile tests by North Korea, was raised on the third day, and was raised in such a way that He was able to walk the 7 miles to Emmaus with two of His own disciples and discourse with them about the Scriptures and what those said about the Christ.
See: most people discount the value of the resurrection to only spiritual or supernatural or metaphysical meaning. It's a nice thing to think about on Easter, I guess -- that Christ's resurrection gives us (the ones called out) a promise of eternal life in Heaven. It's a great idea in fact.
But what most people miss out on is the riches of the Gospel in the resurrection. When Paul tells the Corinthians that Christ died, was buried, and then was resurrected, he doesn't just trumpet the resurrection as a religious or spiritual event: he proclaims that these things were done in accordance with the Scriptures.
You english-speaking people in many ways gloss over that, but when Paul writes that he means the event happened in the way the Scriptures had already said they would happen. That is, history was conformed to what was written in the Scriptures. So in his proclamation, Paul is saying that God's promises in Scripture, and God's truthful in Scripture, are all pointed toward this event. And more importantly, they are also justified or established in this event.
So when Jesus walked out of the tomb, our understanding of history has to now take into consideration and weigh that there is only one account of the events which saw this coming, and which based its reputation as reliable and authoritative on this thing happening. There is only one account of the events of all of history which pointed to this, and was written specifically for the sake of explaining this event. And that account says that Noah built an Ark, and the water covered the Earth, and that this guy who walked out of the tomb said, "They were eating and drinking and marrying and being given in marriage, until the day when Noah entered the ark, and the flood came and destroyed them all." (Lk 17:27)
I believe in Noah's Ark because Scripture is justified as reliable based on its predetermined revelation of the death, burial and resurrection of Jesus, who is Messiah. Jesus' resurrection forces us to stand on God's turf and not on the ground we think looks best to us. And take off your shoes, because this is holy ground.
