The ethics and sanctions are everything in the story of Noah.
The whole reason God cleansed the Earth was because the ethics of everyone had turned into nothing but rule breaking sin. Every rule of the commandments were being broken by sinful and unclean humans, and when you break a rule, there is a sanction.
“And God said unto Noah, The end of all flesh is come before me; for the earth is filled with violence through them; and, behold, I will destroy them with the earth.”
The punishment of the flood was not just because of the broken laws but because of the need to rid the world of the sinful ethics of the people and to start anew with new ethics of love, family and faith.
He had chosen Noah because of his ethics. He was a family man that loved his faith and his family and did what he could to provide and follow the laws.
“These are the generations of Noah: Noah was a just man and perfect in his generations, and Noah walked with God.”
He was not one to receive the sanction because of this. He was the one tasked to help save the world in renewing it.
“ Make thee an ark of gopher wood; rooms shalt thou make in the ark, and shalt pitch it within and without with pitch.”
So he followed the orders of his God and set about collecting the animals and his own family, following the orders to exactly for only getting 7 of each species of clean animal and 2 of every unclean species of animal.
“ Of every clean beast thou shalt take to thee by sevens, the male and his female: and of beasts that are not clean by two, the male and his female.”
“Of fowls after their kind, and of cattle after their kind, of every creeping thing of the earth after his kind, two of every sort shall come unto thee, to keep them alive.”
Noah knew the sanction that was going to take place after all of this was over, but he still followed the orders and thus, he and his family, made of his wife, his three sons, and his sons’ wives were saved along with the animals.
” And Noah did according unto all that the Lord commanded him.”
The sanction of the flood took place while they were safe inside of the ark, cleansing the world of the old and sinful ethics.
“And Noah was six hundred years old when the flood of waters was upon the earth.”
Everything from the earth had gone, it had been cleansed of the sin.
“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.”
And when the flood was over, the sin gone and the world anew, Noah still followed God. He did not turn his back or succumb to sin, his ethics had not changed.
“ And Noah builded an altar unto the Lord; and took of every clean beast, and of every clean fowl, and offered burnt offerings on the altar.”
From these quotes, one can tell that sense Noah was faithful and true; he and his family were saved. While the others’ ethics were the direct cause of God’s wrath.
