How to respond to classical theists who dodge Open Theism arguments

[Clete]

The author of Hebrews said this.

9 But we see Jesus, who was made a little lower than the angels, for the suffering of death crowned with glory and honor, that He, by the grace of God, might taste death for everyone.

Yes, he can summon 12 legions of angels if he wanted. Instead he followed the will of the Father. (unlike the rest of us)

Yes, I'm not disputing that he was made a little lower than the angels but rather what is meant by that. Lower how? or Lower in what way? That is the question we don't really know the answer to.
