When answering this question, we as Christians must remember, logic and rationality can only take us so far. Revelation must take us the rest of the way.
The Holy Trinity consists of The Father, The Son, and The Holy Spirit. Although they are DISTINCT persons, they aren’t SEPERATE.
The Father = God = Thought
The Son = God = Word
The Holy Spirit = God = Breath
However…
The Father ≠ The Son ≠ The Holy Spirit
God is God itself, the thinker. The Father is the The thought. The Son is the word that comes from that thought. The Holy Spirit is the breath that speaks the word. They are Tri-Equal and Tri-Eternal.
