Locust I have tried to answer all your questions
You had eight separate questions and I tried to put altogether in a way you would understand through the Bible Scriptures but it seems like you missed the point . So I would attend to give you another way of examining what I am trying to say. For me Satan is a real energetic person and very dangerous. Now in Joe chapter 1.1-22 is different than Joe chapter 2 .1.13 note that the Angels used to to take their station before their God( why ?) and even Satan enter and to his place , and in jod .1 .7 and arguments between Satan and GOD a row is in the four courts, and everybody was listening to this argument ?( Malicious. jealous .Self-seeking .manslayer), Angel(Satan) carefully used his words of incitement like he did in the garden of eden (genesis 3.1.5 ) and all the spiritual Angels could hear is discussion. And they must have had an assignment on the earth because in job .1..7 he answers, from roaming about and walking about in it . And, Now have you set your sights on my servant JOB.. You see how he questions god's rights of authority. Because you have put a hedge around him and you blissed him . Knows this self-seeking Angel( Satan) attacked Joe by destroying his property and then his family .JOB .1-12.. Now IN JOB 2 -4 vs. four see what he says this malicious satan because he would have killed Joe with some infections or illness so God had to put restrictions on this argument so God said you can not take his soul( life) because we know from genesis.3 .19 . adam and Eve , died eventually and this was because of Satan's malicious lies.
Nailit ( 2) Why was Satan cast to Earth in the first place when God had an entire universe in which to banish him? Seems as though BibleGod was setting Adam & Eve up for a fall.
Locust because people has bebecome unrighteous and disobedience.. the creator use the earth to see if man would prove himself s righteou or unrighteous for the great day of judgment john .5 .28 Adam and eve willfully disobey GOD command
john 5 .28.29. there is to be the judgment ing of the righteous and the unrighteous
Nailit ( 3) If Satan was banished from heaven, then how come the book of Job has him in heaven having a friendly little wager with God
locust this happened when Jesus return to heaven, after his death because it was written( revelation) by apostle john was prisoner on the island of patmos c 96 Revelation 1:1-3 .1.1...2 Jesus gives him a series of visions about the future.
Nailit ( 4) In the Bible, Satan kills Job's children and servants (condoned and allowed by God)
He is not recorded as having killed anyone else in contrast to the millions slaughtered by God.
Locust . You Have to remember that he (God) support his own people and he will protect them and look after them and keep them from anyone how is disloyal to him will be judged.
locust and thats it.satan has killed millions on millions of people in death because of the (lies ) genesis 3. 3 you possibilities will not bie when he told .Eve,, genesis 3.3.4.5 (3) you will positively not die . even touch the fruit you will died , now everyone dies even through sickness or old age doesn’t matter how , we all die .
Nailit ( 5)Why is he seen as previously been known by the name of Lucifer when the word Lucifer (its not a name) is only mentioned one time and in only one version (KJV) of the Bible and even then in relation to a Babylonion king and not a supernatural entity?
