Genesis 7:13 says, In the selfsame day entered Noah, and Shem, and Ham, and Japheth, the sons of Noah, and Noah’s wife, and the three wives of his sons with them, into the ark;  These were the people who would repopulate the earth.  We really aren't told much about Noah's children's relationship with God, but I believe that they must have at least followed the example of Noah.  Verse fourteen states, They, and every beast after his kind, and all the cattle after their kind, and every creeping thing that creepeth upon the earth after his kind, and every fowl after his kind, every bird of every sort.  All the animals were also aboard the ark.  Verse fifteen adds, And they went in unto Noah into the ark, two and two of all flesh, wherein is the breath of life.   Though they went in two by two, we know that the clean animals had seven pairs going in.  I don't believe that Noah had to go hunt and herd the animals, but more that God brought them there and lined them up.  I do have to wonder what people around Noah felt by this time, with a giant boat sitting on dry land being filled with animals, but they were not interested enough to begin to look to Noah or God for answers.  There may be people today who are curious about what is going on in the church, or Christianity, but they are not interested enough to find out.  Like those around Noah, they will miss salvation if they only remain curious.  Verse sixteen says,  And they that went in, went in male and female of all flesh, as God had commanded him: and the LORD shut him in.  We are told that they went in as God commanded them and God shut them in.  When we go to God through faith in Christ as our Savior and Lord, which is what God commands us to do for salvation, then God shuts, or seals, us into His kingdom.  Once we accept Christ, we are God's children forever.  God seals our salvation.  Verse seventeen declares, And the flood was forty days upon the earth; and the waters increased, and bare up the ark, and it was lift up above the earth.  The flood came, just as God had said it would, and Noah and everyone and everything on the ark were safe.  God always keeps His promises.  Verse eighteen adds, And the waters prevailed, and were increased greatly upon the earth; and the ark went upon the face of the waters.  This simply says that as the waiter rose that the ark rose with it.  Verse nineteen continues, And the waters prevailed exceedingly upon the earth; and all the high hills, that were under the whole heaven, were covered.  Verse twenty concludes, Fifteen cubits upward did the waters prevail; and the mountains were covered.  This flood didn't just cover the low areas, but covered the mountains as well.  There was no other place of sanctuary outside the ark, and there is no place of sanctuary spiritually today outside of faith in Christ.  Verse twenty-one says, And all flesh died that moved upon the earth, both of fowl, and of cattle, and of beast, and of every creeping thing that creepeth upon the earth, and every man:  All the animals on land and all the people on the earth died.  Verse twenty-two adds, All in whose nostrils was the breath of life, of all that was in the dry land, died.  The fish survived, because they lived in the water.  Verse twenty-three states, And every living substance was destroyed which was upon the face of the ground, both man, and cattle, and the creeping things, and the fowl of the heaven; and they were destroyed from the earth: and Noah only remained alive, and they that were with him in the ark.  Verse twenty-four concludes, And the waters prevailed upon the earth an hundred and fifty days.  The earth was covered with water for one hundred and fifty days.
