The only reason that the LORD gives for saving Noah is that he is a righteous man. The starting lines of chapter 7 are important for a well-informed understanding of man’s salvation. As in the case of Noah, salvation means salvation from the deserved wrath of the LORD. This is foundational.
Unfortunately for us, none of us is righteous. All have sinned. But the LORD still wants to save us. The cross comes into play. Our salvation is via the righteousness of the one and only son of God, the LORD Jesus Christ. Even here we see a similar picture being portrayed. Noah’s sons and wives get saved because of Noah’s righteousness.
We are introduced to the first 40 days and 40 nights. We shall see several references to the number 40, as we read the rest of the Bible.
At first, we would wonder how Noah managed to get the creatures to corporate and enter the Ark. Fact is that the LORD caused the animals to show up by themselves. Remarkable!
Again we notice the generosity of God in saving the animals. You would expect the LORD not to be bothered too much with things that He would easily create – by word of mouth! The guess is that the LORD is attached to perfection and immortality. The LORD seeks to perpetuate perfection and goodness in creation. The LORD is perfect and what the LORD does is perfect, hence the effort to preserve the perfect work.
