The Word of God is very clear in making the Holy Spirit a person. We are told that you are to “grieve not the holy Spirit of God” (Ephesians 4:30). Well, you can’t grieve an influence, an impersonal force, at all. You can only grieve a person.
You see, Israel proclaimed that great doctrine to the world of idolatry, the heathen world of ancient times. God said to Israel, “Hear, O Israel: The Lord our God [Jehovah, Elohim, the plural God–the Trinity, if you please] is one Lord” (Deuteronomy 6:4). In the midst of idolatry, they were to declare the unique person of God–that God is one.
We are to present one God to a world of atheism. Because it’s changed today–there are not many idolaters with images up in their homes; most homes today have no God at all. But we are to declare before a world of atheism the Trinity: the Father, the Son, and the Holy Spirit.
