This is a question that has been on my mind for a few days, because I was asked about it by a very sweet lady who happens to be a Pentecostal by way of her association. Our Creator is One in essence, yet three in Person. It isn’t a hard thing to understand unless you want to deny God being God! He is God, He is the Holy Spirit of God and He is the Living Word, the Son of God!
I don’t mean that God exists as three gods, He is God in Three Persons, yet all of them…each one is as much God as the other! It is a difficult doctrine to understand unless you have some help from Him!
“And now the Sovereign LORD (the Father) has sent me (the Son), with his Spirit (the Holy Spirit).” Isaiah 48:16
Even at the time that Isaiah was a prophet in Israel, God revealed to Him that He was and is three persons in One. Not three gods, but One God with three persons Who in each are also God. Each person of the Trinity is God, but each has a different function. Just as I am a husband, a father and at one time I was a son before my parents passed into eternity. Three functions in One Person is the most apt description of God as a triune godhead.
Just as all things in the universe have a three-fold nature, so does God. Matter has substance (mass) plus energy and motion; time is made up of past, present and future; space is made up of length, width, and depth or height. Their nature doesn’t make them any less than what they are, but take away even one of their parts and you don’t have matter, space or time anymore.
If you take this to a logical conclusion which many skeptics seem to be willing to overlook, the Son of God is also God the Son! The Holy Spirit is the third Person of the trinity and He is fully God, but His influence in our lives is more of a teacher and leader in spiritual things. It is He that resides in your heart and mine, if we have given our lives to Jesus and asked for Him to come into our lives and our hearts.
The Spirit of God was the Person of the Trinity hovering over the waters before creation. What were the waters? I don’t know, you will have to save that question for God Himself. In either case each part of the Trinity is just as much God as the Other. They perform different functions and do different things in this world and in the spiritual realm, but each of them is still God.
When God told Moses that “No man could see His face and live”, He meant that. Which is why when He hid Moses in the cleft of the rock and allowed him to see His back. Later, when Scripture mentions the Angel of the Lord with a capital “A”, this is the pre-incarnate Christ, not an angel. The Spirit or Holy Spirit is the person of the Trinity which carries out miraculous healings and resurrections and other signs like being understood by someone who doesn’t speak your language. He also prays for us in our time of anguish and doubt when we are so burdened until we can’t say what is necessary.
In reality, it took the intervention of all three to save each person who is a Christian. Think of it this way: God sent His Son to be the atonement for our sins, Jesus died as a human with the nature of God in order to pay the price for humanity’s sins, and the Holy Spirit convicted you of your need for salvation and brought you to the cross to meet Jesus. If it is too hard to understand, ask a little child. The only time that we will know the answers will be when we are standing in His Presence, and even then we may still not understand it.
