It's notable how many times the phrase 'first day of the week' is found in to NT. This lines up beautifully with the first day of the Genesis week and the way in which it pointed to the new creation and the new man. In resurrection Jesus is the first born among many brethren and the beginning of a entirely new creation.
He's called the last Adam and the second man -
And so it is written, The first man Adam was made a living soul; the last Adam was made a quickening spirit. Howbeit that was not first which is spiritual, but that which is natural; and afterward that which is spiritual. The first man is of the earth, earthy: the second man is the Lord from heaven.
(1Co 15:45-47 KJV)
I think that Jesus, in his resurrection didn't actually have to unwrap the grave clothing or even have angels to help him out of it like Lazarus did when Jesus told the people standing by to unwrap him. Instead, Jesus just sat up and stepped out. He didn't even need the stone to be rolled away to leave. The angels rolled the stone away so that men could see that the tomb was empty, it was for their sake. There are no barriers to the resurrection, not cloth or walls or distance or time.
That first day was and is a tremendous day of light. - For God, who commanded the light to shine out of darkness, hath shined in our hearts, to give the light of the knowledge of the glory of God in the face of Jesus Christ.
(2Co 4:6 KJV)
This reminds me of another passage:
For we have not followed cunningly devised fables, when we made known unto you the power and coming of our Lord Jesus Christ, but were eyewitnesses of his majesty. For he received from God the Father honour and glory, when there came such a voice to him from the excellent glory, This is my beloved Son, in whom I am well pleased. And this voice which came from heaven we heard, when we were with him in the holy mount. We have also a more sure word of prophecy; whereunto ye do well that ye take heed, as unto a light that shineth in a dark place, until the day dawn, and the day star arise in your hearts:
(2Pe 1:16-19 KJV)
On the 'holy mount' Jesus began to be revealed in glory when three of the disciples became eyewitnesses of his majesty. Today there is a famous place called the temple mount, but that is not the place referred to as the mount of transfiguration. Two completely different places and not to be confused with one another. Amazingly it is testified that those in whom Christ dwells have a more sure word of prophecy, even more sure than the time that Jesus' glory shone forth on the holy mount. This word is said to be arising in your heart, like the dawning of the day. That is what we are to take heed of, the work of the Lord in the heart, taking place and increasing even as the world is becoming more dark! The holy prophets all spoke of this -
For, behold, the darkness shall cover the earth, and gross darkness the people: but the LORD shall arise upon thee, and his glory shall be seen upon thee.
(Isa 60:2 KJV)
The end result of this is the new man being made manifest and seen by all humanity. But now this life is hid with Christ in God but there is a time when the glory of the Lord shall cover the earth as the waters cover the sea.
For the earth shall be filled with the knowledge of the glory of the LORD, as the waters cover the sea.
(Hab 2:14 KJV)
There is a definite time when the mystery of God, that great work he is doing in his saints, will be finished -
But in the days of the voice of the seventh angel, when he shall begin to sound, the mystery of God should be finished, as he hath declared to his servants the prophets.
(Rev 10:7 KJV)
The mystery of God is Christ in you the hope of glory. It is that glory of which we speak. There is no other hope of glory other than Christ Jesus in your heart. The body is a temple of the Holy Spirit, made clean and set apart for the Lord but the new man created in Christ is the work of God, the operation of God. This is what Paul means when he writes about being changed into his image by the Spirit of the Lord. Not a fading glory as was seen on the face of Moses in the OT but an excellent glory that surpasses the glory of the law in every way. Not fading but increasing, not condemning but justifying, not in part but complete, not a type or symbol but the substance of the resurrection himself, the treasure that we have in an earthen vessel. Whatever happens to the vessel, whether we are changed in the twinkling of an eye or the vessel is dissolved and we fold up this tent, it is sure that we have a building of God, a house not made with men's hands, eternal in the heavens.
