God is the Creator and Ruler of the universe. He has eternally existed as the Father, the Son and the Holy Spirit. The three are coequal and are one God.
Genesis 1:1,26, 27, 3:22, Psalm 90:2, Matthew 28:19, 1 Peter 1:2, 2 Cor. 13:14, 1 John 5:6-8
Before the mountains were born,
before you gave birth to the earth and the world,
from eternity to eternity, you are God. Psalm 90:2
