Jesus is first and foremost, Only-begotten Son of the Living God, as He is True Son, he has the same Nature and Name as His Father, His origin is, eternity Mic 5:2; Matt 2:1-6. He, 'comes forth from the Father' - John 16:28, Prov 8:22-30
So then follows, He is, Word of God by nature, who 'goes forth and will not return empty handed' - Isaiah 55:11 As Moses also affirmed 'man doth not live by bread only, but by every word that proceedeth out of the mouth of the LORD', Jesus confirmed (Matt 4:4). Jesus elsewhere confirms His nature as this living Word by saying 'Verily, verily, I say unto you, Moses gave you not that bread from heaven; but my Father giveth you the true bread from heaven. For the bread of God is he which cometh down from heaven, and giveth life unto the world. Then said they unto him, Lord, evermore give us this bread. And Jesus said unto them, I am the bread of life: he that cometh to me shall never hunger; and he that believeth on me shall never thirst.' These two truths perfectly harmonize the difficulty with subjection.
The Word of God, always obeys the will of God. Or more simply, The Word of God, speaks and performs the mind of the One who speaks.
As Jesus said 'Verily, verily, I say unto you, The Son can do nothing of himself, but what he seeth the Father do: for what things soever he doeth, these also doeth the Son likewise.'
