Is Satan the ruler and god of this world?

Many people mistakenly believe that Satan is the ruler and god of this world. However, the truth is, that there is but one Ruler and GOD of this world and all others. Satan has usurped the position but that doesn't mean it has been given to him to hold.

Here is what the Sovereign LORD GOD ALMIGHTY says,

Isaiah 45:5-6 I am the LORD, and there is no other; apart from Me there is no GOD. I will strengthen you, though you have not acknowledged Me, so that from the rising of the sun to the place of its setting men may know there is none besides Me. I am the LORD, and there is no other.

Isaiah 45:7 I form the light and create darkness, I bring prosperity and create disaster; I, the LORD, do all these things.

Isaiah 45:9 "Woe to him who quarrels with his Maker, to him who is but a potsherd among the potsherds on the ground. Does the clay say to the potter, 'What are you making?' Does your work say, 'He has no hands'?

Isaiah 45:12 It is I who made the earth and created mankind upon it. My own hands stretched out the heavens; I marshaled their starry hosts.

Isaiah 45:16 All the makers of idols will be put to shame and disgraced; they will go off into disgrace together.

Isaiah 45:17 But Israel (not only the physical place or people, but ALL that have called on and chosen as his own, the name of the LORD GOD ALMIGHTY) will be saved by the LORD with an everlasting salvation; you will never be put to shame or disgraced, to ages everlasting.

Isa 45:18 For this is what the LORD says— He who created the heavens, He is GOD; He who fashioned and made the earth, He founded it; He did not create it to be empty, but formed it to be inhabited— He says: "I am the LORD, and there is no other.

Isa 45:21 Declare what is to be, present it— let them take counsel together. Who foretold this long ago, who declared it from the distant past? Was it not I, the LORD? And there is no GOD apart from Me, a righteous GOD and a Savior; there is none but Me.
