death (v.26) — A time is coming when all who will die have died.
He says (v.27) — Psalm 8:6 — The first Adam lost his position over creation, but the second Adam (Christ) never will.
all things (v.27) — emphasized — The Father is the only exception to the “all things.”
when (vs. 27 and 28) = whensoever
then (v.28) = immediately following, with no interval
Son Himself will also be subject (v.28) — having fulfilled the Father’s will. His oneness with the Father will continue eternally.
When it says that He will give up the Kingdom, it does not mean that the Kingdom itself will be terminated. The millennial reign is only the introduction to the eternal reign (Revelation 22:5), and has to crush all rebellion. But the Son ceases to reign as man when the thousand years shall have run their course, though as King of Israel He shall also reign forever. As God He is blessed forever and reigning with the Father and the Spirit forever. That God may be all in all. — Bultema, page 133.
