The Bible does speak f God's Spirit. Now surely God's Spirit is God. There are many biblical passages that point to teheTrinity. Read the opening of the Book of John.
I understand, I was a trinity believer. To the natural look of things in the Bible, its going to look like there are three literal persons in heaven. But if I dig deep in the Word, I will see things differently.
For instance Genesis 1:26 and 1:27 seem to contradict each other. To the natural man, it is a contradiction.
This is when a person has to seek God out with all of his or her heart and ask for the truth and God will reveal it to that person.
Because we know that there is no contradiction in the Word of God.
Mat_5:8 Blessed are the pure in heart: for they shall see God.
Gen 1:27 So God created man in his own image, in the image of God created he him; male and female created he them.
In 1:27, His is singular. What did God mean then by "let us" in verse 1:26?
Jer 10:11 Thus shall ye say unto them, The gods that have not made the heavens and the earth, even they shall perish from the earth, and from under these heavens.
Jer 10:12 He hath made the earth by his power, he hath established the world by his wisdom, and hath stretched out the heavens by his discretion.
That "us" is His attributes. Not persons.
When creating man, He had an attribute of "love" come forward. If God did not send forth the attribute of love then we could not love.
Same way with wisdom. Another attribute of God.
Joy, peace, understanding. All the attributes of God came forward and made man.
Isa 44:8 Fear ye not, neither be afraid: have not I told thee from that time, and have declared it? ye are even my witnesses. Is there a God beside me? yea, there is no God; I know not any.
Isa 44:9 They that make a graven image are all of them vanity; and their delectable things shall not profit; and they are their own witnesses; they see not, nor know; that they may be ashamed.
Isa 44:10 Who hath formed a god, or molten a graven image that is profitable for nothing?
Isa 43:10 Ye are my witnesses, saith the LORD, and my servant whom I have chosen: that ye may know and believe me, and understand that I am he: before me there was no God formed, neither shall there be after me.
Isa 43:11 I, even I, am the LORD; and beside me there is no saviour.
Isa 43:12 I have declared, and have saved, and I have shewed, when there was no strange god among you: therefore ye are my witnesses, saith the LORD, that I am God.
Isa 43:13 Yea, before the day was I am he; and there is none that can deliver out of my hand: I will work, and who shall let it?
Isa 43:14 Thus saith the LORD, your redeemer, the Holy One of Israel; For your sake I have sent to Babylon, and have brought down all their nobles, and the Chaldeans, whose cry is in the ships.
Isa 43:15 I am the LORD, your Holy One, the creator of Israel, your King.
So according to these scriptures, there is no other god but One God.
Deu 6:4 Hear, O Israel: The LORD our God is one LORD:
not two or three.
Exo_34:14 For thou shalt worship no other god: for the LORD, whose name is Jealous, is a jealous God:
Why would God have two other gods in heaven with Him if He is a Jealous God and will not allow any other God before Him?
