(Luke 4:5-7) 5 So he brought him up and showed him all the kingdoms of the inhabited earth in an instant of time; 6 and the Devil said to him: “I will give you all this authority and the glory of them, because it has been delivered to me, and to whomever I wish I give it. 7 You, therefore, if you do an act of worship before me, it will all be yours.” This scripture shows that the devil IS real and that he DOES have authority over the governments. It also shows what he wants, that is worship for himself. THUS, whenever people choose or are mislead into not following the true God and His son Jesus, they are actually worshipping Satan. Even if they believe they are doing good. Psalm 37:10, 11 shows Satan will be destroyed, but when God says the time is right, but we are living in what 2 Tim calls the last days.
That is not his objective, he just wants to show god that humans will be bad and go against god naturally. The world is already under satans control, its even said in the bible. But god will never let the world get destroyed.. So nuclear destruction of the pkanet will never happen.
You seem to know a lot about the devils strategic plan! I am amazed, because I was under the impression his biggest effort was in false belief and religion, not annihilation. But I now stand corrected.
