Vs. 1  I would like to point out 2 of the words in this verse;
From H6663; just: - just, lawful, righteous (man).
Noah was a just and lawful man.  
do^r  do^r
dore, dore
From H1752; properly a revolution of time, that is, an age or generation; also a dwelling: - age, X evermore, generation, [n-]ever, posterity.
This could mean the general  period of time that your life and those your age lived, or it could mean the period of time that all of those like you lived, For instance the whole history of mankind between the fall and the flood. Personally I believe it means both in this case, had the flood happened during Enoch's time perhaps the same words could have been said of him as was said of Noah but the flood came during Noah's time and Noah obeyed.  It also was the end of an age, after the flood the lifespan of people would decrease by so much that Noah's great, great, great, grandson would die at 239 years old and 10 years BEFORE Noah does at 950.  Abraham would die at 175 years old 35 years before his great, great, great, great, great, great, great grandfather Shem at 600 years old. So that people that were born 500 years after the flood had a life span of 100- 200 years instead of the 900 years that was common before the flood. An age had ended, perhaps the 1st age of man but I count it as the second overall but the first after man became a mortal being and certainly the first age of God's plan of redemption. It is interesting that in the New Testament  it is often the case when Jesus talks about the end of the world, He uses the word that means AGE, and sometime the words that means a specific area or system not necessarily the whole planet but more about that when we get there.
Vs. 2 - 10
God tells Noah to go in the ark and take with him the animals. There are those that say that there wasn't enough room in the ark for all the animals but I have seen studies on the subject that have convinced me that there was, I wont go into it much but the point was made that even the dinosaurs would have fit if you consider that God never said bring in ADULT animals, many of the larger ones could well have been young.
Notice that there are already clean and unclean animals and that God tells them to take 7 pairs of the clean animals and 2 of the unclean. This might be a bit confusing but consider this, though God had told them what to eat in the garden and it was all vegetarian we have no idea when men began to eat animal flesh. We do know however that as early as Able men were slaughtering animals for sacrificial purposes. It is not unreasonable to assume that people were eating animals from the early days and though we have no record of God pointing out which to eat and which to avoid it is clear that by this point God and man are aware what is considered clean and what is not but as we will see God will allow them to eat whatever they want after the flood only to clarify later what was clean and what was not in great detail.
God tells him that in 7 days He will cause it to rain 40 days and nights and that He would destroy every living thing except what was in the ark.  Jesus tells us that;
Luk 17:26  And as it was in the days of Noah, so shall it be also in the days of the
son of man. Luk 17:27  They did eat, they drank, they married wives, they were
given in marriage, until the day that Noah entered into the ark, and the flood
came, and destroyed them all
Noah obeyed God and it says he was 600 years old when the flood happened which according to my reckoning was 1651 years after Adam started counting his age whether that was at creation or at the fall, if you think about it there was little reason to know your age if you were to live forever.

Vs. 11 - 24
The short story over the rest of the chapter is that God brought the flood and everything not in the ark dies but I would like to point out a few things.
In verse 11 it is specific to the day as to when this happened 2nd month 17th day and it says that the fountains of the great deep were broken up and the windows opened. The website I posted before is a small museum in the state I live in (Texas) which has a lecture every 1st Saturday of the month. The owner of the museum is Professor Carl Baugh who also has a program on TBN for those of you who can get it. His theory is that before this time all the land mass was together and that when these fountains of the great deep broke up the continents of North and South America split off and traveled west until they got to the general area they are now. When this happened, the waters under the earth and oceans, of which there are still plenty consider the vents that were recently discovered on the ocean floor which vent very hot WATER into the bottom of the ocean, were released into the upper atmosphere. This caused a sudden flash freeze to cover the poles where there have been found woolly mammoths that were frozen with green grass in their mouths. I tend to agree with this and it is the only explanation for these mammoths being frozen in a climate where green grass would grow.
Also I have a theory about the flood, anyone that has seen a flood knows that debris tends to collect and lands on dry ground in a bunch according to the eddies and currents. To me this explains why dinosaur bones are often found in groups and it also would explain why the fossils we find seem to be in layers that are imho incorrectly interpreted as being thousands and millions of years apart. It seems logical that the seashell creatures would sink right away, the more flesh covered creatures last because they would float for a while first. One last bit, when Mt. St. Helens erupted in the early 80s the mud flows laid down   layers of sediment that astonished the scientists. Their commented that they would have said it was millions of years of sediment had they not known how it occurred. So in conclusion, modern science believes it impossible that the flood could have happened as it is written so they cannot consider it in any of their theories of how we got here and the evidence they see must be explained in some other way. I look at it like this, if I want to go to Canada but I insist on going due west from here (Texas) I will get to a lot of places but I will never get to Canada until I admit I am wrong and change direction. Science can believe whatever they want but until they consider all the possibilities they cannot come to the truth. Same goes for knowing God, it doesn't matter how fervently a person believes if what they believe isn't what God has said. God is not obligated to honor what people believe no matter how many people believe it, BUT God IS obligated to honor what He has said, it is our job to find out what that is and to adjust our lives accordingly.
Well that's a really good place to end this week but let me add this little bit more,
Vs. 16   God SHUT them in,
Vs. 19  ALL the high hills under the WHOLE heaven were covered (meaning it was world wide not just one area as is said by some),
Vs. 23 and Noah only remained alive, and they that were with him in the ark.
Vs. 24 and the waters prevailed upon the earth a hundred and fifty
