C. Old Testament passages suggest the different roles of the Persons of the Trinity

1. The Father
Psalms 68:4–5; 89:26

2. The Son
Psalms 2:12; 22:1–31; 89:26–27; Isaiah 63:9

3. The Holy Ghost
Isaiah 6:3; 63:10

IV. God the Eternal Father
A. First person of the trinity

B. While all persons of the trinity are equally God, there is a distinct order to the Godhead
Matthew 28:19; 1 John 5:7; 1 Corinthians 11:3; 15:24-28; John 14:16, 26; 16:7, 13–15

C. Receiver of petitions. Proper prayer is made:
1. To the Father
Luke 11:1–2; Matthew 26:53; John 16:23

2. In the name of the Son.

Because the Lord Jesus died for us, the Father grants our requests made in His name. That is why you will often hear Christians start their prayer with something like “Dear heavenly Father” and end their prayer with something like “in Jesus’ name, amen.”
John 15:16; 16:23, 26–27

3. Through the Holy Ghost
“Likewise the Spirit also helpeth our infirmities: for we know not what we should pray for as we ought: but the Spirit itself maketh intercession for us with groanings which cannot be uttered. And he that searcheth the hearts knoweth what is the mind of the Spirit, because he maketh intercession for the saints according to the will of God” (Romans 8:26–27).

Jude 20; Luke 12:12
