So you see all of us from Peter to now as still being in the last days?? I guess we are going to have to agree to disagree. All of the urgency and immanency that they wrote about 2,000 years ago, in your mind, has been and remains imminent. The thing about the no moon and sun doesn't apply to our physical realm. It applies to the spiritual realm. When Christ did what He said He would do in those John 6 and 11 passages you cite, He rose them up to the spiritual realm AKA Heaven, not back here to Earth.
The thing about the moon and sun does apply to our physical realm "the temporal" .The temporal is needed when rightly diving the word of God. It reveals the spiritual or the gospel hid from natural man. That seen is used to reveal the unseen eternal gospel;.
2 Corinthians 4:18 While we look not at the things which are seen, but at the things which are not seen: for the things which are seen are temporal; but the things which are not seen are eternal.
It applies to the spiritual realm as a unseen law of faith . Parables do not make the literal without effect. It can add to it possibly to enrich. Like Manna taste like honey. Eat just enough to keep in mind that the better thing that accompanies salvation is he will not forget the good works we offer towards his name. No self edification like the many in Mathew 7.
It would appear the glory of God as the presence of God. Is the light in verse 1 .of Genesis 1. God is light .God giving his signature of his glory :."And it was Good". That glory would seemed to have departed in day 3. In day 4 for it would seem the corruption time keepers began its usage for Day and night.. . called "under the sun"
In the new order the spiritual use of the literal Sun and moon was given to complete the doctrine. No more night.
And I saw no temple therein: for the Lord God Almighty and the Lamb are the temple of it.And the city had no need of the sun, neither of the moon, to shine in it: for the glory of God did lighten it, and the Lamb is the light thereof. And the nations of them which are saved shall walk in the light of it: and the kings of the earth do bring their glory and honour into it. And the gates of it shall not be shut at all by day: for there shall be no night there. Revelation 21:22-25
