“The Spirit of God was hovering over the face of the waters” (Gen. 1:3, ESV). “Spirit” is from the Hebrew, ruwach, “wind, breath, spirit.” The noun, ruwach, is singular in number. It speaks of only one Person—the Spirit of God. Jesus said that the Holy Spirit is like the wind that blows(John 3:8). Luke wrote that the Spirit came on the day of Pentecost like a mighty, rushing wind (Acts 2:2).
Moses wrote that it is the Spirit of Elohim. This Spirit of Elohim was “hovering over the face of the waters” (ESV, NKJV). The verb, “hovering,” is like the brooding of a hen while hatching her eggs or taking care of her young. (Clarke) To hover is to move to and fro over something. This was the work of the Spirit of God in creation. He was moving about, giving life, giving form, and giving direction to all creation.
The Trinity acted in unity in creation. God created the heavens and the earth. But the Word was with God and the Word was God. The Spirit of God was hovering over the waters. Thus, we see three persons acting in creation.
There is only one God, the Bible declares. But this one God is elohim—plural. The Word was with God and the Word was God. There is also the Spirit of God.
Thus, these three persons of God are one God. This one God is three persons—the Trinity.
