There are works and then there are works

In the midst of a violent, corrupt world, the Lord has this man, Noah, whose faith was most clearly made manifest by his works. This is a crucial point that all people who love the Lord and the great promises of salvation through grace alone, by faith in Jesus, must remember. Noah could have had all the faith possible, but had he not acted on that faith and obeyed the Lord's commands, he and his family would have been swept away with the rest of the world in the Flood (see Heb. 11:7). That should be a great object lesson for all of us who, day by day, claim the righteousness of Jesus for us as the only hope of our salvation: A faith that isn't manifested in obedience isn't really faith at all.

Gen 7:1 And Jehovah said to Noah, You and all your house come into the ark, for I have seen you righteous before Me in this generation.

Gen 7:2 You shall take with you every clean animal by sevens, the male and female. And take two of the animals that are not clean, the male and female.

Gen 7:17 And the flood was upon the earth forty days. And the waters increased and bore up the ark, and it was lifted up above the earth.
18 And the waters prevailed and were increased greatly upon the earth. And the ark floated upon the face of the waters.
19 And the waters prevailed exceedingly upon the earth. And all the high hills that were under the whole heaven were covered.
20 The waters prevailed fifteen cubits upward, and the mountains were covered.
21 And all flesh that moved upon the face of the earth died, of birds, of cattle, of animal, and of every creeping thing that creeps upon the earth; and every man,
22 all who breathed the breath of life, of all that was in the dry land, died.
23 And every living thing which was on the face of the earth was destroyed, from man to cattle, and to the creeping things, and the fowls of the heavens. And they were destroyed from the earth, and only Noah was left, and those that were with him in the ark.
24 And the waters prevailed upon the earth a hundred and fifty days.

I think Tuesday's study brings in an element of the animals that Noah was obviously acquainted with.

The above quoted text clearly distinguished between clean and unclean animals long before there ever was a Jewish nation, which makes me wonder why Christians say this was only for the Jewish people.

he isnt recorded as eating them.

Very probably. However, the ratio of 7:1 in the ark indicates that God had also alimentary purposes in mind, for the period after the flood.

Gen 8:20 And Noah built an altar to Jehovah. And he took of every clean animal, and of every clean bird, and offered burnt offerings on the altar.

Gen 9:3 Every moving thing that lives shall be food for you. I have given you all things, even as the green herb.
