Where did satan come from? Did God create him?
The Bible indicates that he was once a perfect, free willed spirit creature whose magnificence led him to envy the worship given to the Creator. He had no opportunity in the spirit realm to gain worship because all the other spirit beings were his equal....all he could be was their leader if he had opportunity to form a coup.
With the creation of man, satan saw his chance to hijack lower beings and become the god he wanted to be. In a calculated move, he targeted the newbie, the more vulnerable and less educated of the pair. When she was alone, he used a serpent to ask some subtle questions, designed to plant seeds of doubt in her mind regarding God's intentions and his motives in keeping a "knowledge of good and evil" under his own jurisdiction. She fell for the whole thing and disobeyed a direct command that carried the death penalty. Her response to the devil's question revealed that she knew what she was doing. It was blatant disobedience motivated by self interest.
When her husband came along and she offered him the fruit, he understood all the implications of what she had done....so he had two choices.....join her and die with her, or reject her offer and lose her. In forcing Adam to make that emotional choice, the devil took a calculated risk....and it paid off. He was the target all along. He got to the man through the woman. (Romans 5:12) The fate of the entire human race rested on his choice.
Satan was an appointed guardian angel in Eden, "a covering cherub" according to Ezekiel 28:12-15.....
“‘“You are sealing up a pattern, full of wisdom and perfect in beauty. 13 In Eʹden, the garden of God, you proved to be. Every precious stone was your covering, ruby, topaz and jasper; onyx and jade; sapphire, turquoise and emerald; and of gold was the workmanship of your settings and your sockets in you. In the day of your being created they were made ready. 14 You are the anointed cherub that is covering, and I have set you. On the holy mountain of God you proved to be. In the midst of fiery stones you walked about. 15 You were faultless in your ways from the day of your being created until unrighteousness was found in you."
No one knows satan's real name. It isn't Lucifer, as many assume. God has never allowed satan's real name to be revealed. He is known only by his titles......"satan" (resister) and "devil" (slanderer).
The devil knew what he was doing when he tempted the woman, but he stupidly underestimated God's response to his scheme. Humans had the ability to live forever because of having access to the "tree of life" in the garden. He probably assumed he could have worshippers who would never die. But God barred access to the tree of life and satan's scheme backfired on him. Because his worshippers would die, he had to constantly recruit more. He is tireless in his efforts.
He targets all humans with the same temptations he has always used. He doesn't change his tactics, because he knows they work. Only those individuals who have formed their own close relationship with the true God can resist him, just like Jesus did.
When Jesus was tempted after his baptism, the devil used appeals to self interest to undermine Christ's resolve to remain faithful. In Luke 4:5-8 it is revealed that rulership of this world was "delivered" to satan, and that he could give authority to 'whomever he wished'. This is why Jesus told us to be "no part of this world". (1 John 5:19; John 15:18-21)
With each temptation, Jesus responded with "It is written", referring always to God's word. Those who face the subtle temptations of the devil today need to do the same. If the big things don't get you, the little things will.
There is not one scripture that says satan rules over a place called "hell"....that is a concocted falsehood. Hell in the Bible is simply mankind's common grave. People sleep peacefully there. They are not conscious and are not capable of any thought or activity. (Ecclesiastes 9:5, 10) There is no immortal part of man that lives on after death. That is satan's way of perpetuating his first lie...."you surely will not die". When human's succumbed to death, he had to lead them to believe that they lived on......invisibly in another realm. That is not what God told Adam. (Genesis 2:17; Genesis 3:19)
The devil knows his fate, but the only way he can win (in his own mind) is to take as many down with him as he can....therefore, everyone is a target. He has no compassion for the innocent. No love even for the wicked.
Does God stop him from trying to tempt humans away from true worship? No, because then we all have an opportunity to prove who we really are in our own hearts and minds. If we search for God with a humble and open heart devoid of pre-conceptions about what "we" want to be true, God will find us.....we will not be left floundering in spiritual darkness. If our hearts are closed and we search only for what "we" want in a religion, then God will never "draw" us to his truth. (John 6:44)
We have to want what he is offering. He will never alter his plans to suit selfish humans.
The Bible says that
"satan keeps transforming himself into an angel of light" (2 Corinthians 11:14-15) pretending to be what he is not. People fall for his lies as they have always done, but now, in this "time of the end" he has intensified his efforts. He is no longer subtle....he is in all our faces. The entertainment industry is a great vehicle for dispensing his propaganda. Sex and violence are his stock in trade and always have been. He even targets our children with spiritistic overtones even in their cartoons. Spiritism too is one of his favourite tactics. (Deuteronomy 18:9-12)
Those forewarned are forearmed to fight the good fight and stand firm in the face of colossal odds. We can do it if we have God on our side. If we don't then there is the real possibility that the end of this system of satan's rulership will be the end of our existence as well.
This makes a great deal of sense to me.
