By St. Gregory Palamas
The pre-eternal, uncircumscribed and almighty Logos and omnipotent Son of God could clearly have saved man from mortality and servitude to the devil without Himself becoming man.
He upholds all things by the word of His power and everything is subject to His divine authority (cf. Heb. 1:3). According to Job, He can do everything and nothing is impossible for Him (cf. Job 42:2 LXX).
The strength of a created being cannot withstand the power of the Creator, and nothing is more powerful than the Almighty.
But the incarnation of the Logos of God was the method of deliverance most in keeping with our nature and weakness, and most appropriate for Him who carried it out, for this method had justice on its side, and God does not act without justice.
