Freedom on Earth

Contrary to popular opinion, the Bible reveals that Satan and some of his demons were not confined to hell after their initial expulsion from heaven. Indeed, the Old Testament shows that, before the first coming of Yeshua the Messiah, Satan and the demons continued to have access to the very throne of God.

Now there was a day when the sons of God came to present themselves before the Lord, and Satan also came among them.Job 1:6

Again there was a day when the sons of God came to present themselves before the Lord, and Satancame also among them to present himself before the Lord. Job 2:1  

Then he showed me Joshua the high priest standing before the angel of the Lord, and Satan standing at his right hand to accuse him. Zechariah 3:1

 If  some demons are obviously free to propagate evil in the world, there are Scriptures which indicate that a portion of the evil angels are currently restrained in a type of spiritual prison.

And the angelswho did not keep their own position, but left their proper dwelling, he has kept in eternal chains in deepest darkness for the judgment of the great Day. Jude 6

For if God did not spare the angels who sinned, but cast them down to hell and delivered them into chains of darkness, to be reserved for judgment; II Peter 2.4

. . . He went and preached tothe spirits in prison, 20 who formerly were disobedient, when once the Divine longsuffering waited in the days of Noah, while the ark was being prepared, in which a few, that is, eight souls, were saved through water. I Peter 3:19  

Clearly, the Bible teaches that there are at least two different groups of fallen angels; those who can move around freely and those who are currently locked up in "chains of darkness."
