The Old Testament promises that Messiah will have dominion of the works that God has created. Psalm 8:6 You (Father-God) have made him (Son of Man, i.e. Christ) to have dominion over the works of Your hands; You (Father-God) have put all things under his feet. From this verse, some have tried to emphasize the superiority of the human species. However, Ephesians appears to temper that notion.
Eph 1:19-22 [That you would know] the exceeding greatness of God’s power toward us who have believed, according to the working of His mighty power which He wrought when He raised him (Jesus) from the dead, and set him at His own right hand in the heavens, Far above all principality, and power, and might, and dominion, and every name that is named, not only in this age, but also in that which is to come: And has put all things under his (Jesus’) feet, and gave him, the head over all, to the church.
Dominion and authority belong to Christ. Through the Christian experience, we get to understand the greatness of God’s power toward us (not our power toward something else). Jesus was placed far above all other powers not from only this timeframe, but also over those from the age to come.
The Father gave HE WHO IS ABOVE ALL to the church as the head of the organization. To be part of this living body, one must be receiving directives from the head and should be completing them as a faithful subject in His kingdom. The Father puts all things under Christ’s feet. So as we carry out HIS bidding, the authority and position of Jesus blankets us.
