This is an illustration of how the Jewish/ proto-Christians conceived of their two Gods: the Father and the Son
John 1.1: In the beginning was the Word, and the Word was with God, and the Word was God.
The early Jewish proto-Christians viewed their God as made of words. It was not made of wood, bronze, clay, iron, silver or gold like the gentile Gods, but only of words.
One could also pick out a second God made up of the words of God that God had spoken in Hebrew Scriptures. Thus the entire expression “In the beginning God created the heavens and the earth. Now the earth was formless and empty, darkness was over the surface of the deep, and the Spirit of God was hovering over the waters. And God said, “Let there be Light” was included in the first God, but only the expression “Let there be Light” was included in the second God. This was a second God called “Son of God.”
The later Gospel tales took this concept and made it into stories telling of the incarnation of this second God, this “Son of God” on Earth.
