(Matthew 4:13-16) Further, after leaving Nazʹa·reth, he came and took up residence in Ca·perʹna·um beside the sea in the districts of Zebʹu·lun and Naphʹta·li, 14 so as to fulfill what was spoken through Isaiah the prophet, who said: 15 “O land of Zebʹu·lun and land of Naphʹta·li, along the road of the sea, on the other side of the Jordan, Galʹi·lee of the nations! 16 The people sitting in darkness saw a great light, and as for those sitting in a region of deathly shadow, light rose on them.”
So your just hoping this truth will go away are you?
Your verse showing a future prophesy of a grate light as in Jesus saying I am come "a"light does zero justification for your denying that God is the true light ref to in John 1:9.
Again the LIGHT "IS" Gods word and God is Light and that which is born of Spirit is Spirit again showing He is this true light and we know from Jesus himself, 4 times in John Jesus says he was speaking the words of his God and Fathers = The Fathers true light, Spirit of Truth, his words.
