I am speaking of his dual nature. Not, his physical being.
Colossians 2:9
For in him dwells all the fullness of the Godhead bodily.
Philippians 2:7
Expanded Bible
7 But he ·gave up his place with God and made himself nothing [L emptied himself].
He ·became like [ took the form of] a ·servant [slave; bond servant]
and was born ·as a man [in the likeness of humanity/men].
Philippians 2:8
And ·when he was living [ being found in appearance/likeness] as a ·man [human being], he humbled himself and was fully obedient to God, even ·when that caused his [to the point of] death—death on a cross.
it shouldn't be so hard to understand His dual nature when considering our struggle with the reality of our dual nature as righteous man and sinner. Though it may be argued that He ever struggled with it, He Is, Righteous Man and Lord God.
