This article looks at the unified nature of GOD.
The Godhead is comprised of the Father, Word/Son (Jesus), and the Holy Spirit. The three deities, which are collectively called GOD, are perfectly and completely unified. Because they are unified, the Scriptures state numerous times that there is "one GOD."
Here are a number of Scriptures that speak to the unity of all three Persons in the Godhead.
Father, Word and Spirit were Involved in Creation
