Satan is the god of this world. He is powerful. He is supernatural. But he will burn in Hell fire forever and ever.
Well I don't think he is the god of this world since the bible clearly depicts the Trinity as having ultimate power over this world:
Daniel 2:20-21
20 Daniel answered and said, Blessed be the name of God for ever and ever: for wisdom and might are his:
21 And he changeth the times and the seasons: he removeth kings, and setteth up kings: he giveth wisdom unto the wise, and knowledge to them that know understanding:
but I did find this about Lucifer:
Isaiah 14:12-17
New King James Version
The Fall of Lucifer
12 “How you are fallen from heaven, O Lucifer, son of the morning!
How you are cut down to the ground, You who weakened the nations!
13 For you have said in your heart: ‘I will ascend into heaven, I will exalt my throne above the stars of God; I will also sit on the mount of the congregation On the farthest sides of the north;
14 I will ascend above the heights of the clouds, I will be like the Most High.’
15 Yet you shall be brought down to Sheol, To the lowest depths of the Pit.
16 “Those who see you will gaze at you,
And consider you,
saying: ‘
Is this the man who made the earth tremble, Who shook kingdoms,
17 Who made the world as a wilderness And destroyed its cities,
Who did not open the house of his prisoners?’
