The Ascension of Christ was to Supreme Power and Dignity

Was it not necessary for the Christ to suffer these things and then to enter His glory?”

…which He exerted in Christ when He raised Him from the dead and seated Him at His right hand in the heavenly realms,

…far above all rule and authority, power and dominion, and every name that is named, not only in the present age but also in the one to come.

…who has gone into heaven and is at the right hand of God, with angels, authorities, and powers subject to Him.
