Rev 5:12 Says with a loud voice, Worthy is the Lamb that was slain to receive power, and riches, and wisdom, and strength, and honor, and glory, and blessing.
Jesus is the Lamb of God, slain from the foundation of the world. He is the inspiration and summation of all human and heavenly revelation. (Alpha and Omega).
Worthy is that Lamb. The legal process for him to possess all power and glory has been completed. He has been found worthy to receive all power and glory on earth and in heaven. The importance of this is that it was done for us. He received it after we became one with him in his resurrection. Same life, same victory!
Col 2:9 For in him dwelleth all the fulness of the Godhead bodily.
