As I reflected on the trinity, and asked for guidance, divine understanding, a symbol to help me understand this, which is not meant to be understood as a theological dichotomy as it has been done so far, aspect of God, I suddenly had the image of a diamond. One diamond, but with several facets. You will see a different facet reflected depending on the light of that moment, the angle, but it is that same diamond, not a separate diamond. Such is God. With that and the Bible, connecting Old and New Testament, things got clearer and clearer.
Start with Genesis 2:7 where God breathes life into humanity (in the first two chapters Adam means humanity or mankind in Hebrew, not singular one person) and then go to John 20:22 where Jesus/God breathes life into the apostles, a regenerative spirit, new life in unison with God. That tells us that they are one and the same, God/Jesus/Holy Spirit, Jesus/God/Holy Spirit. This is our first indication that it is one entity, one God, just as the Old Testament tells us. I reiterate, God does not have Multiple Personality Disorder and is not three split personalities in one. He is Omnipotent and Omnipresent, so he can manifest in multiple modalities at the same time.
When we look at Romans 1:3-4 and John 14:7-12, we see that if we have seen/known Jesus, then we have seen/known God, as well as the Holy Spirit. How can that be? It is because it is all one and the same, one God, simply different manifestations for different purposes and goals. In Ephesians 4:4-6 it's emphasized One God/Lord, One Baptism, One, not Three in One, but One!! In Revelation 1:4 we have the Him ho is was and will be, and in 22:1 we see one thrown for the Father and the Lamb, thus they are one. Again, the Holy Spirit gave me the image of the multi-faceted, but singular diamond and the shopkeeper wearing several hats, but ONE shopkeeper.
Jesus tells us that he is the way, truth and the life and no one can get to the father but through him. Yes, because he is the one who gave humanity life and will destroy that which is an abomination to him on judgment day. In 1John:1 we are given to understand that Jesus is God himself manifest as life, manifest as a man, to live amongst us, to be the perfect sacrifice for us. Only God/Elohim himself manifesting in human form could be the perfect sacrifice and example of a perfect life. Again when we have the voice over Jesus in the Jordan and the dove, we must remember that God is Omnipotent and Omnipresent, so he can manifest in multiple places, forms, but is still one God, one entity, one source, not three. Something more to ponder.
