[The following was taken from a portion of Faith of God University's Course On The Godhead By Ryan Hicks.]
SCRIPTURES TEACHING TWO AND THREE PERSONS IN THE GODHEAD
When studying these Scriptures notice how God talks to His Son, and His Son talks to the Father. Notice how the Holy Spirit is said to be the Spirit of God, this means that He is from God. Notice how God calls the Holy Spirit His Spirit. These Scriptures are clear that two and three Persons Each called God have been seen at the same time, have talked to each other, and have been sent from one another. Thus, it is abundantly clear from Scripture that there are Three Persons in the Godhead.
