Murjahel, I love your posts, but I have to disagree with this one. With all due respect, this is eisegesis, threading unrelated scripture to support a popular albeit errant view. It seems to be a common exercise among conservative/fundamentalist believers. Ill stick with the OP view.
Your same argument is used against Isaiah 53 referring to Jesus' crucifixion... I reject that argument there, and here. The 'law of double reference applies, and is necessary due to the circumstances of Isaiah's day.
Isaiah is one of the hardest books to interpret due to several factors... I saved it for last of all the prophetic books in my study...
Isaiah 6:8-10 (KJV)
8 Also I heard the voice of the Lord, saying, Whom shall I send, and who will go for us? Then said I, Here am I; send me.
9 And he said, Go, and tell this people,
Hear ye indeed, but understand not; and see ye indeed, but perceive not.
10 Make the heart of this people fat, and make their ears heavy, and shut their eyes; lest they see with their eyes, and hear with their ears, and understand with their heart, and convert, and be healed.
We still find some critics that do not see, do not understand..
This was not an easy feat for Isaiah to prophesy to the spiritual darkness then of things they were not prepared to understand. Therefore, much of the prophecy of Isaiah is still difficult for us to understand. The law of double reference here in the discussed passage is obvious, and impossible not to admit... too many parts are unexplainable otherwise.
Isaiah gave a message of near hopelessness to a people who did not want to hear him. They had eyes that would not see, ears that refused to listen. Their hearts were hard and stubborn. He was told they would stay that way until their country was waste land, and all had been taken away captive. That is a horrible calling, a hard set of sermons to preach.
The grand and glorious visions given to Isaiah were to aid him in his receiving of the message of judgment. Had he not been given hope, the hopelessness of the message to those people would have been immeasurably hard. To explain of Christ's details in crucifixion, and know that the hearers would be totally confused by it, so a double reference hid it from their eyes, but we in our times see it plainly. The same with the explanation of the fall of Lucifer, it was thought by most then, and a few even now to be reference to something else, but only the law of double reference explains what Isaiah was truly referring to...
The Messianic revelation, His birth, His life, His work, His wondrous victory at the cross, was all revealed long ago to Isaiah. He needed that revelation, and he was given it. The sceptics may scoff, we can let them scoff. The critics may look for proofs that the books of Isaiah are forgeries by liars. Yet, Jesus Himself validated those books, and allowed the New Testament to record those validations. I would rather listen to the words of Jesus, than the sceptics and critics who have degrees but no spiritual awareness of the faith.
Isaiah was allowed to view Immanuel, and know that Jesus was God with us. Many Jewish clergy in the time of Jesus coming had not figured that out yet. Jesus said that the sufferings of the Messiah were clearly taught in the Old Testament, and they are in Isaiahs writings.
Yet, the blindness of scepticism kept many in Jesus time from seeing these passages. The same with the passage here about 'Lucifer'... and no "Lucifer' is not the planet Venus, and he was created prior to Venus, not the other way around. We all have a star named by God after us, does that make us a 'star'?
