Even Christians pray to God as if He is someone other than the One manifested in our Lord Jesus Christ.   

This is error reflecting a lack of understanding of the scriptures.   Primarily, that error was introduced at Nicea because there were believers in Christ as Son but who denied that He is also Father.   

Ignorance results in weakness.   

Jesus told us to speak to His Holy Spirit Father in His name - the name, Jesus.   

Jesus is the name and personification of the Unknown God.   

Then Paul stood in the midst of Mars` hill, and said, You men of Athens, I perceive that in all things you are too superstitious. Act 17:22 Superstition comes from a tiny bit of truth combined with a load of untruths.

For as I passed by, and beheld your devotions, I found an altar with this inscription, TO THE Unknown God.     Whom therefore you ignorantly worship, him declare I unto you. Act 17:23 All false gods are the creation of people who do not know the Holy Spirit of Christ Jesus.

The Lord that made the world and all things therein, seeing that he is Lord of heaven and earth, dwells not in temples made with hands; Act 17:24 It doesn`t even make sense that the Creator of all things would live in something that His creation made.

Neither is worshipped with men`s hands, as though he needed any thing, seeing he gives to all life, and breath, and all things; Act 17:25 Nothing that we can do is suitable for worship.      Acceptable worship is in acknowledging and receiving His Word Of Truth by which we receive Him, know Him and live in Him.

And has made of one blood all nations of men for to dwell on all the face of the earth, and has determined the times before appointed, and the bounds of their habitation; Act 17:26 Life is in the blood.     The life that is in every man is of the Holy Spirit who is life.      A scientific fact is stated here.     All men have the same DNA structure.     They are of one kind and produce after that kind.      What are the times appointed?         → time itself    → seasons    → ages What are the bounds of our habitation?         → water    → air    → land.      Man cannot live without these three physical creations.

That they should seek the Lord, if haply they might feel after him, and find him, though he be not far from every one of us: Act 17:27 The Holy Spirit fills the universe and beyond but He manifests Himself to a person when they receive the Lord Jesus Christ who reveals the Truth about Him.

For in him we live, and move, and have our being; as certain also of your own poets have said, For we are also his offspring. Act 17:28 The `Him` is the Holy Spirit.     He has begotten us as New Spirit beings of His own self.

Forasmuch then as we are the offspring of the Lord, we ought not to think that divinity is like unto gold, or silver, or stone, graven by art and man`s device. Act 17:29 We are the offspring of the Holy Spirit by His Word expressed in and through Christ Jesus.

And the times of this ignorance the Lord winked at; but now commands all men every where to repent: Act 17:30 Notice that the Lord commands people to repent.     He is not pleading with them to repent.     Maybe commanding is what we should be doing?

Because he has appointed a day, in the which he will judge the world in righteousness in that man whom he has ordained; whereof he has given assurance unto all men, in that he has raised him from the dead. Act 17:31 The Judgment will be conducted by Christ Jesus, the express image of His Holy Spirit.

Before He manifested in the flesh God was only Spirit and Soul as described in Joh 1:1.    He had no certain Body.   

Whenthe Holy Spirit Father impregnated Mary Mat 1:18,20, the Word (Soul) became flesh and dwelt among us Joh 1:14 .   

Because the Spirit and Word are One Joh 1:1, the manifestation of Christ Jesus brought into One being the Spirit Soul And Body of the One True And Living God Deu 6:4 .
