Revelation 21:22-23 KJV
 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.
The I Am!!! POWERFUL!!!
The Father and The Son are the Temple… The Father and The Son are The Light.
The people of God in times past, as some now also, they knew the seventh day Sabbath come from one new moon to another: In Heaven we shall know the Sabbath the seventh day come by the Father and the Son (Y’shua), for Christ is The Lord of the Sabbath.
Isaiah 66:22-23 KJV
 For as the new heavens and the new earth, which I will make, shall remain before me, saith the Lord, so shall your seed and your name remain.  And it shall come to pass, that from one new moon to another, and from one sabbath to another, shall all flesh come to worship before me, saith the Lord.
Isaiah 24:23 KJV Then the moon shall be confounded, and the sun ashamed, when the LORD of hosts shall reign in mount Zion, and in Jerusalem, and before his ancients gloriously.
Isaiah 60:19-20 KJV
 The sun shall be no more thy light by day; neither for brightness shall the moon give light unto thee: but the Lord shall be unto thee an everlasting light, and thy God thy glory.  Thy sun shall no more go down; neither shall thy moon withdraw itself: for the LORD shall be thine everlasting light, and the days of thy mourning shall be ended.
Hebrews 4:1-16 KJV
 Let us therefore fear, lest, a promise being left us of entering into his rest, any of you should seem to come short of it.  For unto us was the gospel preached, as well as unto them: but the word preached did not profit them, not being mixed with faith in them that heard it.  For we which have believed do enter into rest, as he said, As I have sworn in my wrath, if they shall enter into my rest: although the works were finished from the foundation of the world.  For he spake in a certain place of the seventh day on this wise, And God did rest the seventh day from all his works.  And in this place again, If they shall enter into my rest.  Seeing therefore it remaineth that some must enter therein, and they to whom it was first preached entered not in because of unbelief:  Again, he limiteth a certain day, saying in David, To day, after so long a time; as it is said, To day if ye will hear his voice, harden not your hearts.  For if Jesus had given them rest, then would he not afterward have spoken of another day.  There remaineth therefore a rest to the people of God.  For he that is entered into his rest, he also hath ceased from his own works, as God did from his.  Let us labour therefore to enter into that rest, lest any man fall after the same example of unbelief.  For the word of God is quick, and powerful, and sharper than any twoedged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart.  Neither is there any creature that is not manifest in his sight: but all things are naked and opened unto the eyes of him with whom we have to do.  Seeing then that we have a great high priest, that is passed into the heavens, Jesus the Son of God, let us hold fast our profession.  For we have not an high priest which cannot be touched with the feeling of our infirmities; but was in all points tempted like as we are, yet without sin.  Let us therefore come boldly unto the throne of grace, that we may obtain mercy, and find grace to help in time of need. …
Revelation 21:25 KJV And the gates of it shall not be shut at all by day: for there shall be no night there.
Revelation 22:5 KJV And there shall be no night there; and they need no candle, neither light of the sun; for the Lord God giveth them light: and they shall reign for ever and ever.
