Thank you for sharing the scripture that actually refutes your prior argument.
You cannot argue on that platform while ignoring Gods own words wherein He states, He is one. And beside him there is no Savior. [The Book of Isaiah chapter 43] Which would necessarily revoke the idea of God, Holy Spirit, and Savior Jesus, as the triune.
Immanuel, "God with us". [The Book of Isaiah chapter 7 and the Book of Matthew chapter 1]
God cannot be more clear than that.
Jesus was/is God.
He was man before His Baptism though He was divinely formed in Mary's womb. After Baptism Jesus/Immanuel started His ministry fully empowered by His indwelling Holy Spirit nature. Which descended upon the flesh of the man knitted together in Mary's womb by Holy Spirit God, so all would witness this and hear the Father state aloud unto all there, this is my Son in whom I AM well pleased. [The Book of Matthew chapter 3]
Jesus Himself referred to Himself as, I AM. Which was the name God told Moses to give unto Pharaoh in the event Pharaoh asked Moses who had sent him. [The Book of Exodus chapter 3]
