Matt. 16:28, “Verily I say unto you, There be some standing here, which shall not taste of death, till they see the Son of man coming in his kingdom.
Luke 9:28, “And it came to pass about an eight days after these sayings, he took Peter and John and James, and went up into a mountain to pray.”
The 8th Day principle is very powerful, not only in relation to our sonship but also to the cleansing and acceptance of Lepers into the fold or congregation as in Lev. 14.
Lev. 14:10, “And on the eighth day he shall take two he lambs without blemish, and one ewe lamb of the first year without blemish, and three tenth deals of fine flour for a meat offering, mingled with oil, and one log of oil. 11 And the priest that maketh him clean shall present the man that is to be made clean, and those things, before the LORD, at the door of the tabernacle of the congregation.”
The resurrection body that Jesus wore when He came out of the grave described for us the nature of the gloried body that speaks of His sonship.
Rom. 1:3, “Concerning his Son Jesus Christ our Lord, which was made of the seed of David according to the flesh; 4 And declared to be the Son of God with power, according to the spirit of holiness, by the resurrection from the dead.”
It was with this Body of Glory that He appeared to the disciples after the resurrection with the doors locked, and they thought He was ghost.
Luke 24:39, “Behold my hands and my feet, that it is I myself: handle me, and see; for a spirit hath not flesh and bones, as ye see me have. 40 And when he had thus spoken, he shewed them his hands and his feet.”
This was the Body revealed to the Apostles on the Mount of Transfiguration, a fore-state of things to come in the Feast of Tabernacles, hence Peter requested they be there because of the glory it carried.
And Jesus being the firstborn among many brethren; and that in everything He must take or have the preeminence, it therefore follows that whatever experience he has and revealed we must of necessity have the same, since we are brethren and of the same family and stock.
Paul rightly described for us the nature of the bodies we should put on should we drop the flesh in death.
2 Cor. 5:1, “For we know that when this tent we live in now is taken down-when we die and leave these bodies-we will have wonderful new bodies in heaven, homes that will be ours forevermore, made for us by God himself and not by human hands. 2 How weary we grow of our present bodies. That is why we look forward eagerly to the day when we shall have heavenly bodies that we shall put on like new clothes. 3 For we shall not be merely spirits without bodies. 4 These earthly bodies make us groan and sigh, but we wouldn’t like to think of dying and having no bodies at all. We want to slip into our new bodies so that these dying bodies will, as it were, be swallowed up by everlasting life. 5 This is what God has prepared for us, and as a guarantee he has given us his Holy Spirit.” TLB.
That is the nature of the glorified body that we are talking about. But what Jesus did show is that God is not planning that we drop the flesh only before attaining to this Body of Glory.
So we read in Ampl. Phil 3:20,
“But we are citizens of the state (commonwealth, homeland) which is in heaven, and from it also we earnestly and patiently await [the coming of] the Lord Jesus Christ (the Messiah) [as] Savior, 21 Who will transform and fashion anew (Transfiguration) the body of our humiliation to conform to and be like the body of His glory (Transfiguration) and majesty, by exerting that power (which raised from the dead) which enables Him even to subject everything to Himself.”
Now where is He coming from to change our body into the same image and Body of His Glory? It is from within us where He resides, hence
“Christ in you, the hope of glory,” Col. 1:27.
Besides, this Son of God that showed up from within Jesus the Lamb of God is our life. See it here;
Col. 3:3, “For [as far as this world is concerned] you have died, and your [new, real] life is hidden with Christ in God. 4 When Christ, Who is our life, appears, then you also will appear with Him in [the splendor of His] glory,” Amp. Can you see it?
So then here is the fullness of redemption which is “Spirit” “Soul” and “Body” (1Thes. 5:25) in God’s agenda as “Passover”, “Pentecost” and “Tabernacles” as we read;
Rom. 8:22, “For we know that the whole creation groaneth and travaileth in pain together until now. 23 And not only they, but ourselves also, which have the first fruits of the Spirit, even we ourselves groan within ourselves, waiting for the adoption, to wit, the REDEMPTION OF OUR BODY. 24 For we are saved by hope: but hope that is seen is not hope: for what a man seeth, why doth he yet hope for?”
So the FIRSTFRUIT which is the Holy SPIRIT within us is the guarantee that we have in expecting the glorification (transfiguration) of our bodies and this is the hope that we are waiting for which is what the scriptures finally say in;
Rev. 21:2, “And I John saw the holy city, new Jerusalem, coming down from God out of heaven, prepared as a bride adorned for her husband. 3 And I heard a great voice out of heaven saying, Behold, the TABERNACLE (dwelling place ) OF GOD IS WITH MEN, and he will dwell with them, and they shall be his people, and God himself shall be with them, and be their God.”
This then is the 8th Day Glory of the workings of God that declares our full sonship.
