In the year of King Uzziah's death I saw the Lord sitting on a throne, lofty and exalted, with the train of His robe filling the temple. (please read vv.1-5 again)
Jesus Christ is the highest authority in this universe!
"I saw the Lord sitting on a throne." In Isaiah's vision of the Lord, the Lord wasn't battling for authority; He wasn't struggling over the throne. No, He was sitting in absolute power and authority over all things.
In John 12:41, the Apostle John quotes a verse from later in this chapter of Isaiah and clearly states that it was Jesus that Isaiah saw on the throne. Jesus Himself said to the disciples, "All authority has been given to Me in heaven and on earth" (Matthew 28:18).
In Ephesians 1:20-23, the Apostle Paul declares that God the Father "raised [Jesus] from the dead and seated Him at His right hand in the heavenly places, far above all rule and authority and power and dominion, and every name that is named, not only in this age but also in the one to come. And He put all things in subjection under His feet, and gave Him as head over all things to the church, which is His body, the fullness of Him who fills all in all."
Today I encourage you to physically get on your knees before Jesus Christ and speak with the One who has all authority in heaven and on earth.
