Satan (Lucifer) has always been after God's throne. In fact, this is found in Isaiah 14:12-15:
How art thou fallen from heaven, O Lucifer, son of the morning! how art thou cut down to the ground, which didst weaken the nations!
For thou hast said in thine heart, I will ascend into heaven, I will exalt my throne above the stars of God: I will sit also upon the mount of the congregation, in the sides of the north:
I will ascend above the heights of the clouds; I will be like the most High.
Yet thou shalt be brought down to hell, to the sides of the pit.
No surprise that Satan's organizations claim Adonay (God) to be evil. And as for the Illuminati...Illuminati=illuminated. Satan appears as an angel of what? Light!
and again in Thessalonians 2:2-12
not to be quickly shaken in mind or excited, either by spirit or by word, or by letter purporting to be from us, to the effect that the day of the Lord has come.
Let no one deceive you in any way; for that day will not come, unless the rebellion comes first, and the man of lawlessness is revealed, the son of perdition, who opposes and exalts himself against every so-called god or object of worship, so that he takes his seat in the temple of God, proclaiming himself to be God.
Do you not remember that when I was still with you I told you this?
And you know what is restraining him now so that he may be revealed in his time.
For the mystery of lawlessness is already at work; only he who now restrains it will do so until he is out of the way. And then the lawless one will be revealed, and the Lord Jesus will slay him with the breath of his mouth and destroy him by his appearing and his coming.
The coming of the lawless one by the activity of Satan will be with all power and with pretended signs and wonders, and with all wicked deception for those who are to perish, because they refused to love the truth and so be saved.
Therefore God sends upon them a strong delusion, to make them believe what is false, so that all may be condemned who did not believe the truth but had pleasure in unrighteousness.
and again: (Revelation 16:13-16)
And I saw, issuing from the mouth of the dragon and from the mouth of the beast and from the mouth of the false prophet, three foul spirits like frogs; 14 for they are demonic spirits, performing signs, who go abroad to the kings of the whole world, to assemble them for battle on the great day of God the Almighty. 15 ("Lo, I am coming like a thief! Blessed is he who is awake, keeping his garments that he may not go naked and be seen exposed!") 16 And they assembled them at the place which is called in Hebrew Armaged'don
