This is theological doublespeak. You're trying to justify unjustifiable. Jesus' kingship and the kingdom were indeed inaugurated and established on earth at the beginning of His earthly ministry. He possessed kingdom authority and power on earth over the seen and unseen realm. Demons, men and nature were subject to His Word. That is plain to see during His earthly mission. His sovereign reign and heavenly coronation began after His resurrection and ascension. From there He rules over His new creation and all creation. There is nothing that is not under His feet.
Ephesians 1:19-23 speaks of: “the exceeding greatness (megethos or magnificence) of his power to usward who believe, according to the working of his ‘mighty power’ [Gr. kratos ischus or great dominion force and ability], Which he wrought in Christ, when he raised him from the dead, and set him at his own right hand in the heavenly places, Far above all principality, and power, and might, and dominion, and every name that is named, not only in this world, but also in that which is to come: And hath put all things under his feet, and gave him to be the head over all things to the church, Which is his body, the fulness of him that filleth all in all.”
Christ reigns in majesty and glory at the right hand of majesty today over His enemies. He has already defeated all His enemies. He is king over the kings and kingdoms of the earth. He is Lord and reigns over all principalities and powers, rulers of darkness, and spiritual wickedness in high places. He exercises sovereign kingly power over all His enemies until He makes them His footstool. There is nothing that is not under his feet. Jesus Christ is indeed Lord!
This passage confirms the absolute authority that Christ now enjoys and reveals the unlimited scope of His current rule. It explicitly illustrates the current sovereign reign of Christ over all His enemies from the “right hand” of majesty on high.
Philippians 2:9 says, “wherefore God also hath highly exalted him, and given him a name which is above every name.”
He reigns today over the seen and the unseen world making every power and every authority “subject unto him.”
1 Peter 3:22 says, that Christ, “who is gone into heaven, and is on the right hand of God (now!!!); angels and authorities and powers being (currently!!!) made subject unto him.”
Those who question Christ’s current reign do great assault upon the truth of God’s Word and undermine the current sovereign kingly position that He now assuredly holds.
Heaven’s authority is bestowed upon Christ. He is God! Colossians 2:9-10, 14-15 confirms: "For in him dwelleth all the fulness of the Godhead bodily. And ye are complete in him, which is the head of all principality and power … Blotting out the handwriting of ordinances that was against us, which was contrary to us, and took it out of the way, nailing it to his cross; And having spoiled (or divested or disarmed) principalities and powers, he made a shew of them openly, triumphing over them in it.”
He is risen and He is reigning! He is ruling over everything! This is happening right now! Check out the actual original text and check out the tenses involved. Christ’s universal rule, which is found in His divine character, exercises supreme authority over everything and everyone that exists. This dominion is seen in His sovereign dealing with mankind, whether it is with an individual person or with accumulation of nations – all are subject to his controlling power and ultimate influence. Such authority could be justly described as Christ’s providential kingship.
Colossians 1:15-17 addresses the great sovereign reign of Christ over all creation. Stating, Christ, “Who is the image of the invisible God, the firstborn of every creature: For by him were all things created, that are in heaven, and that are in earth, visible and invisible, whether they be thrones, or dominions, or principalities, or powers: all things were created by him, and for him: And he is before all things, and by him all things consist.”
This is completely comprehensive. Christ is shown to be the ruler of all dominion and power. He is a sovereign God today. Satan is submitted to His authority. Christ is king over all the earth. Can I remind you He reigns over His enemies now as sovereign king? With the Premillennial reasoning they divest Christ of His rightful power.
These passages couldn’t be stronger in outlining where supreme authority lies today. Christ sovereignly reigns in kingly power over all creation.
