While I do not accept the twisted logic of the Trinity, because it goes against too many things in the Bible, assuming for the moment Jesus is, somehow, God, in some way, could it be that Jesus has given a hint of himself in scripture?
Jesus refers to Himself as the Alpha and the Omega - the beginning and the end. No where does Jesus claim He himself is eternal. John claims that the Word - was at (In) the beginning - he does not say the Word was before the beginning. Now keeping in mind the audience Jesus was speaking to, He had to explain in terms they understood - that God was His “father”. If Jesus tried to explain that God the Father was an eternal being outside of the space time continuum, the audience would not have understood. Likewise, were Jesus here today, He still may not be able to explain to our limited minds, what God, and He, are. But if we take what He said at face value, essentially if He is God, perhaps what He is - is the physical, temporal aspect of an Eternal God of Spirit? That He was, essentially, the beginning of time and He will be the end of time. At the end of time, there would be no need for an additional “aspect” of God, just like once the new Jerusalem is in place and we live with God, there is no need for that “aspect” of God represented by the Spirit - because the eternal God the Father will be living with us.
Just a thought
