Satan who is God's antagonist is the god of this world. He took the dominion from Adam when he fell and has been the great prince, the ruler of the powers of this world ever since. The world has been lying in his lap since that awful rebellion of Adam in the Garden of Eden. He is our arch-enemy. He wars against us. He works by deception. He fools people and he wins all the times. It's only by the grace of God that we are ever saved and delivered. Thanks be to the intervention of the Spirit of God that any of us is loosed from the chains and clutches of Satan that is holding mankind.
