The Authority of Jesus Christ is given to Him by The Father. It was always given, never borrowed, never withdrawn. The Son is entrusted with Authority equal to His Father. He keeps that trust by exercising His authority always in deference to His Father.
Jesus had choices!
“During the days of Jesus’ life on Earth, He offered up prayers and petitions with loud cries and tears to The One Who could save Him from death, and He was heard because of His reverent submission. Although He was a Son, He learned obedience from what He suffered” (Hebrews 5:7-8)
It is Christ Jesus that died, yea rather, that was raised from the dead, who is at the right hand of God, who also maketh intercession for us. This intercession resonates with John 17:22, which refers to the “heavenly communion” between Christ and God the Father.
