Genesis 1:28 “God blessed them, (mankind, whom He had created in His own image), and God said to them ,’Be fruitful and multiply.'”
Genesis 9:1 “And God blessed Noah and his sons and said to them, “Be fruitful and multiply, and fill the earth”.
Genesis 12 “Now the LORD said to Abram, “Go forth from your country, and from your relatives, and from your father’s house, to the land that I will show you; And I will make you a great nation, And I will bless you, and make your name great; And so you shall be a blessing; And I will bless those that bless you, And curse those that curse you. And in you all the families of the earth will be blessed.”
The progression of the blessings of God suggest that the arrival of Abram on the scene, and his obedience to the call of God, marks a new beginning for all humanity. Much like Adam who fell with the eating of the fruit of the tree, and the attempt to atone for his sin by making his own coverings, it was Jehovah that adequately covered Adam’s nakedness, an act of salvation, a new beginning.
In like manner as Noah sinned in his drunkenness, it took someone else, to cover his nakedness, another act of salvation, a new beginning.
So, as we find out in this passage, when Abram sins, by not trusting Jehovah in Egypt, but in fear of what ‘might’ happen, he schemes to protect himself by calling Sarai his sister, instead of his wife. As a result the Pharaoh takes Sarai into his haram, to be prepared for becoming yet another wife for himself. But Jehovah struck Pharaoh’s house with great plagues, protecting Sarai, and Abram also. It seems that Pharaoh was more spiritually aware than Abram at this point in time. So Sarai was taken back to Abram and then escorted out of Egypt.
The blessings of God are not dependent on the works of mankind, as we see in these men’s lives, they were all prone to wander, to stray from complete obedience to Jehovah, they were sinful men with a knowledge of good and evil yet no enabling power to resist. In fact they were very much like us, who before salvation had no enabling power to resist sin. Jehovah protected them to bring about a completion to His promise to Adam to provide a covering, a salvation, ‘a seed that will bruise the head of satan.’ As Jehovah reveals in the coming passages, a promised son for Abram, who will believe that promise and it will be reckoned to him as righteousness.
Jehovah made covenants with each of these men, Adam, Noah, and Abram, and he fulfilled them each in time to come, which proves Him to be a faithful God, who will also be faithful to complete His promise to keep His New Covenant with mankind. Which is forgiveness of sins, and everlasting life through faith in Jesus Christ. We also have a throne of Grace where we find enabling grace, that is, ‘mercy and help in the time of need.’ These men of old had no power to resist sin, we do.
