In my opinion, 'Lucifer' is referring to the Babylonian king, not a pre-fallen Satan.
Think about this:
5 And he led him up, and showed him
all the kingdoms of the world in a moment of time.
6 And the devil said unto him, To thee will I give all this authority, and the glory of them: for it
hath been delivered unto me; and to whomsoever I will I give it. Lu 4
'Lucifer' is referring to Satan through his proxy the king of Babylon.
Think about this:
I will no more speak much with you, for
the prince of the world cometh: and he hath nothing in me; Jn 14:30 [see John 18:20 for "the world" defined]
Looky who came, the proxy:
Judas then, having received the band of soldiers, and
officers from the chief priests and the Pharisees cometh thither with lanterns and torches and weapons. Jn 18:3"
Think about this:
14 And
Jehovah God said unto the serpent, Because thou hast done this, cursed art thou above all cattle, and above every beast of the field; upon thy belly shalt thou go, and dust shalt thou eat all the days of thy life:
15 and I will put enmity between thee and the woman, and between thy seed and her seed: he shall bruise thy head, and
thou shalt bruise his heel. Gen 3
Who did the bruising? The proxy of course:
and how
the chief priests and our rulers delivered him up to be condemned to death, and crucified him. Lu 24:20
44
Ye are of your father the devil, and the lusts of your father it is your will to do. He was a murderer from the beginning, and standeth not in the truth, because there is no truth in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father thereof. Jn 8:44
Think about this:
10 to the intent that now unto
the principalities and the powers in the heavenly places might be made known through the church the manifold wisdom of God, Eph 3
12 For
our wrestling is not against flesh and blood, but against the principalities, against the powers, against the world-rulers of this darkness, against the spiritual hosts of wickedness in the heavenly places. Eph 6
These "principalities and powers in the heavenly places" are manifested through their proxies in this time realm.
