Studies in Genesis
And God saw that it was good. And God blessed them, saying, “Be fruitful and multiply and fill the waters in the seas, and let birds multiply on the earth.” And there was evening and there was morning, the fifth day. (Genesis 1:20-23 ESV)
I do not think we have a good understanding of what God means when He “blesses” someone or something. God uses a word which in its most primitive form means to kneel before as when one bestows an honor upon another. Instead of towering over one blessed the one blessing comes down to a lower level. Blessings are gifts given from a heart attitude of pleasure with the one receiving the gift. Imagine a father kneeling to give a gift to his young child.
Here, God bestows upon creation, specifically the sea and air creatures, His desire for His creatures to be fruitful and multiply, each after their own kind. These animals are to fill the earth. God is completely involved in His creation on Earth. Did He lower Himself, showing Himself less than who He is, to give a blessing? No. Did He raise up any creatures, making them more than they are, to receive the blessing? No. He, the eternal God and the eternal Great, brought Himself into His creation giving His creation intrinsic value.
Everything He has done to this point has prepared the universe, solar system, the Earth, ready and more than able to sustain and propagate life. He, Himself, does more than sustain life. He increases life according to the laws of nature binding creation and His good pleasure.
However, Jesus did lower Himself without decreasing any of His divinity. Jesus, God, the Son, set aside His eternal position and lowered Himself into His creation, to bless those made in His image.
Have this mind among yourselves, which is yours in Christ Jesus, who, though he was in the form of God, did not count equality with God a thing to be grasped, but emptied himself, by taking the form of a servant, being born in the likeness of men. And being found in human form, he humbled himself by becoming obedient to the point of death, even death on a cross. Therefore God has highly exalted him and bestowed on him the name that is above every name, so that at the name of Jesus every knee should bow, in heaven and on earth and under the earth, and every tongue confess that Jesus Christ is Lord, to the glory of God the Father. (Philippians 2:5-11 ESV)
As we will see, He created Man, all people, for an intimate relationship with Himself. We are uniquely created for intimacy with God. So, loving all intimately, He knelt down and blessed a rebellious people, humbling Himself to the place of a servant and giving a gift of eternal life.
