"Before the universe existed, there was only God—but He was not
alone.
God is a Trinity—the Persons of the Father, Son, and Holy Spirit all
share in the same divine nature, and they are one God. This aspect of
God’s nature was not fully revealed in the Old Testament, but there are
some intriguing hints of plurality in the Godhead in the Old Testament.
For instance, while contemplating the incomprehensibility of God, Agur,
the author of Proverbs 30, says:
Who has ascended to heaven and come down? Who has gathered the wind in
his fists? Who has wrapped up the waters in a garment? Who has
established all the ends of the earth? What is his name, and what is his son’s name? Surely you know! (Proverbs 30:4).
Agur laments his ignorance (30:1 ff). The knowledge of eternal truths
and power over the creation implied in the first questions is only
possessed by God.
In Jesus’ prayer, often called the ‘High Priestly Prayer’ because of His
intercession for believers, Jesus asks, “And now, Father, glorify me in
your own presence with the glory that I had with you before the world
existed” (John 17:5). " CMI
