Jesus Christ, when He came into the flesh was not 'just a man' especially blessed of the Father, He was God in the flesh, He was the same God of the OT and had that same mind while in the flesh. He did not lose His God status when He became a flesh and blood man.
Col 2:9 For in Him dwells all the fullness of the Godhead bodily;
Mat 1:23 “Behold, the virgin shall be with child, and bear a Son, and they shall call His name Immanuel,” [fn] which is translated, “God with us.”
He was the embodiment of God, He had the Spirit without measure (John 3:34), so He was able to do all those supernatural things because of who He was. But He took on the flesh fully so as to experience what we do, but He certainly retain that mind and understanding of who and what He was - that is the mind of God and that's how He overcame the world. That same Spirit is what the elect are begotten with and are learning to perceive within ourselves.
Phl 2:5 Let this mind be in you which was also in Christ Jesus,
v.6 who, being in the form of God, did not consider it robbery to be equal with God,
He was "equal" as in He was fully one with the Father and that certainly was while He was flesh as well.
John 3:13 “No one has ascended to heaven (after His resurrection) but He who came down from heaven (made a little lower than the angels), that is, the Son of Man who is in heaven (at all times).
John 17:21 “that they all may be one, as You, Father, are in Me, and I in You; that they also may be one in Us, that the world may believe that You sent Me.
That is our hope of glory, to be as Christ is totally one with the Father, through Christ.
mercy, peace and love
