So what is in front of your eyes? Three gods, one god with some assistants who have certain powers, a god his son and a force(spirit)?
The Trinitarian doctrine is difficult to reason because humans aren't God and we are confined to a vision of existence that is limited by our intelligence and senses.
Simple scriptural proofs:
In the first chapter of Genesis, God(the Father) speaks creation into existence. God's Spirit 'moves upon the face of the deep' in that same chapter. In the NT, 1 Chapter of John. "The Word" is identified and further placed at creation. Later Jesus affirms, "I and the Father are one" and "If you have seen me you have seen the Father."
How God makes the Trinity works, is tough to figure out, fortunately we receive faith so we don't have to know the mechanics and all the innerworkings of something to believe and confess that it exists.
Oh please with the 3 gods shenanigans! I have answered this question repeatedly. If you truly want an answer, go look through my posts, although I suspect you won't, because you don't.
Here's another one for you. All things were created by the Son.
Col 1:13-19
(13) Who hath delivered us from the power of darkness, and hath translated us into the kingdom of his dear Son:
(14) In whom we have redemption through his blood, even the forgiveness of sins:
(15) Who is the image of the invisible God, the firstborn of every creature:
(16) For by him were all things created, that are in heaven, and that are in earth, visible and invisible, whether they be thrones, or dominions, or principalities, or powers: all things were created by him, and for him:
(17) And he is before all things, and by him all things consist.
(18) And he is the head of the body, the church: who is the beginning, the firstborn from the dead; that in all things he might have the preeminence.
(19) For it pleased the Father that in him should all fulness dwell;
