Mt 4:12-16, Lk 2:25-32, Jn 1:9-12, Jn 8:12, Jn 12:44-46, Rev 21:23
In the Old Testament, it was said that God would let the light of His glory shine upon us. (Isa 60:1-2)
Isa 60:1 Arise, shine; for thy light is come, and the glory of the Lord is risen upon thee. 2 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.
As the Old Testament prophesied, the light of God's glory was shone upon the Gentiles. (Matthew 4:12-16, Luke 2:25-32)
Matthew 4:12 Now when Jesus had heard that John was cast into prison, he departed into Galilee; 13 And leaving Nazareth, he came and dwelt in Capernaum, which is upon the sea coast, in the borders of Zabulon and Nephthalim: 14 That it might be fulfilled which was spoken by Esaias the prophet, saying, 15 The land of Zabulon, and the land of Nephthalim, by the way of the sea, beyond Jordan, Galilee of the Gentiles; 16 The people which sat in darkness saw great light; and to them which sat in the region and shadow of death light is sprung up.
Luke 2:25 And, behold, there was a man in Jerusalem, whose name was Simeon; and the same man was just and devout, waiting for the consolation of Israel: and the Holy Ghost was upon him. 26 And it was revealed unto him by the Holy Ghost, that he should not see death, before he had seen the Lord's Christ. 27 And he came by the Spirit into the temple: and when the parents brought in the child Jesus, to do for him after the custom of the law, 28 Then took he him up in his arms, and blessed God, and said, 29 Lord, now lettest thou thy servant depart in peace, according to thy word: 30 For mine eyes have seen thy salvation, 31 Which thou hast prepared before the face of all people; 32 A light to lighten the Gentiles, and the glory of thy people Israel.
The light of God's glory has come to this earth. That is Jesus. But the Israelites did not welcome him. (John 1:9-12)
John 1:9 That was the true Light, which lighteth every man that cometh into the world. 10 He was in the world, and the world was made by him, and the world knew him not. 11 He came unto his own, and his own received him not. 12 But as many as received him, to them gave he power to become the sons of God, even to them that believe on his name:
Jesus is the light of the world. He who believes in Jesus does not walk in darkness, but he has the light of life. (John 8:12, John 12:44-46)
John 8:12 Then spake Jesus again unto them, saying, I am the light of the world: he that followeth me shall not walk in darkness, but shall have the light of life.
John 12:44 Jesus cried and said, He that believeth on me, believeth not on me, but on him that sent me. 45 And he that seeth me seeth him that sent me. 46 I am come a light into the world, that whosoever believeth on me should not abide in darkness.
There is no need for the sun and moon in heaven. Because God and Christ Jesus are light. (Revelation 21:23)
Revelation 21:23 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.
