Does this include after His second coming and throughout eternity?
I would say yes, based on...
-He received a glorified human body that ate fish after his resurection, it was that body that ascended into heaven, not just Jesus' Spirit.
-He will be worshiped as THE Lamb for all eternity (Rev. 5).
-Scripture says he "ever lives to make intercession for us." and "there is one mediator between god and man, the MAN Jesus Christ." There is no indication that this priestly role has an ending to it, and therefore no END to when Jesus Christ ceases being a "man".
-1 Cor. 15: points to a Son who will be over all, yet subject to his heavenly father for all eternity.
