Daniel 7:14
And to Him was given dominion, glory and a kingdom, that all the peoples, nations and men of every language might serve Him. His dominion is an everlasting dominion which will not pass away; and His kingdom is one which will not be destroyed”
Contrary to the doctrine of the Jehovah’s Witnesses, Hebrews 12 teaches that the first century saints were receiving the consummated Messianic kingdom in fulfillment of Daniel 7:14, through the establishment of the New Covenant. Jesus’ rule and reign over sin and death exists in His New Creation.
