I'm still of the opinion it's the Spirit, not the Son...
here's another reason why:
Proverbs 8:1-3 Does not wisdom cry out, And understanding lift up her voice? 2 She takes her stand on the top of the high hill, Beside the way, where the paths meet. 3 She cries out by the gates, at the entry of the city, At the entrance of the doors:
Isaiah 42:1-2 "Behold! My Servant whom I uphold, My Elect One in whom My soul delights! I have put My Spirit upon Him; He will bring forth justice to the Gentiles. 2 He will not cry out, nor raise His voice, Nor cause His voice to be heard in the street.
they seem to have quite different ways of operating no?
