This conflicting description of a single being could not have come from a rational mind. It came from the HolySpirit who would fulfil these words in Christ Jesus.
Jesus was born of woman and His HolySpirit and so He is the MightyGod, the EverlastingFather. This means that the Father begat Himself!
The HolySpirit is the Spirit of Jesus. Jesus is the body of the HolySpirit. We are made in the image of our Creator. We are SpiritSoulAndBody and so also is our Creator. His name is Jesus.
