What is the form of our Creator?
We need only look at man who was made in His image Gen 1:26.
The HolySpirit formed Jesus in Mary`s womb for the purpose of manifesting Himself in the body of Jesus.
Since the HolySpirit did this, Jesus did not think it presumptuous for Him to be equal with the HolySpirit.
It is this thinking in His mind and heart that enabled Him to speak the words of the HolySpirit and by the power of the HolySpirit to do the works of the HolySpirit - just as He had done in the beginning when He created all things.
