For Yeshua’s Inheritance, the one new man represents, perhaps, better than any other particular expression, His inheritance in a way that includes the Bride and the Priesthood.
As the Bride, Yeshua is our beloved Bridegroom and inheritance, and we are His: the wife inherits all things that are her husband’s; and as the Son of God, Yeshua/Jesus is promised the inheritance of all things from His Father.
As the Priesthood, YHVH — the Creator and Redeemer covenant-making God who was, and is, and is to come — is our inheritance, and we are being called out into something new together now to stand before Him on behalf of our peoples — whether we are Jewish or Gentile now; yet as one new man, we are neither going to be Jewish or Gentile, male or female, but, rather, as the Body of Christ — our Head and Husband who is King of kings and Lord of lords — something inclusive of all.
As the Bride and the Priests, we are preparing to rule and reign with Messiah/Christ in our resurrected bodies for the 1000-year Millennial Kingdom over Israel and the other nations, in final preparation for that which is perfect to come in the new Heavens and new Earth forever and ever!
