I would like to know the reason.Is god testing us?or is Satan more powerful than God?
Thanks.
God does not kill Satan because God loves Satan -though there is much more to the story.
God is responsible for the circumstances which allowed Satan to come to exist.
God actually created the being Lucifer -the cherub who eventually became the "devil" (Satan -adversary) -but did not create him as an adversary. He did knowingly allow it to potentially happen by creating this cherub with creativity -which requires the ability to make choices. Add to this the fact that he was a new creature -essentially ignorant (though extremely powerful and talented) -and the potential then existed for him to question God. God told him what was good to do -and not good to do -and he travelled to suspect that God was trying to keep him from becoming something greater -by keeping him from knowing both good AND evil. God knew both good and evil, because he had designed all things and knew what would do harm. Satan set out to prove his theory -and used his position (as one of three archangels over a third of all the other angels) to deceive a third of the angels -and lead a coup against the throne of God. These are what we know as the demons.
Essentially, Lucifer (now Satan) is no different than any other sinner -except in power, and most importantly, intent. Some sin ignorantly -some sin wilfully (Sin is defined as the transgression of the law of God). He was simply the first to do so.
God does not want any of those he created to be destroyed -or to destroy.
However, any who refuse to obey God (which causes destruction, as his law is based on what exists) will eventually be destroyed if they do not turn from their ways.
God will not allow destruction to continue indefinitely -whether by man or demon...
...but he has allowed Satan and the demons to affect mankind -just as he allows us to affect each other -so that we all might learn from the experience. We were all once completely ignorant -and travel to understand. It is an extremely harsh lesson, but there is nothing that we can destroy which God cannot renew -no harm that cannot be healed -no pain that cannot eventually be removed from memory once the lesson is learned.
A very good example is the book of Job.
Job was a pretty righteous dude -one of the most righteous, in fact.
Then God brought up the subject of Job to Satan -not the other way around!
Satan did not disturb God wanting to harm Job, but God had it in his mind to teach both Job AND SATAN a valuable lesson.
God asked Satan if he had considered his servant Job.
Satan said Job obeyed God because God blessed him -and if he cursed him, Job would also curse God.
So God allowed Satan to do some very bad things to Job and his family.
Notice that Satan needed God's permission to do anything to Job.
God is in control. No demon or man can do anything unless God allows it -and he allows it knowing he can eventually heal it -and that if we do not experience the fruits of evil it will always be a temptation.
The only way to eventually COMPLETELY remove the temptation to do evil is to experience it (for those who are not willing to simply "do the math" in their heads -and the two thirds of the angels which did not sin are seeing the example without doing it.) God did not force us to do evil -but knew it was inevitable that someone eventualluy chose to do so. So he prepared for the eventuality -and can make it right. As we are creative beings, making it right requires that we CHOOSE right -and he can also help us make that choice.
We actually give Satan more power over us than we do God when we refuse to obey God -but God is still in control -and has declared the end from the beginning.
Some might think it blasphemous, but if Satan were to truly repent, God would accept him. God views him as we would an errant child.
However, he does have a choice -and if any absolutely refuse, they will be removed from the equation.
God did not have to allow Satan and the demons to affect us -but does so for a purpose -and will later make all things new -and wipe away all tears.
...then he will make us like himself -with the same sort of body and creative power.
