Humanity shares Planet Earth with angels, some of whom are invisible, evil enemies that we must resist to overcome sin. These sinning angels, referred to as demons, live on despite their rebellion, unlike humans who die as a result of sin. Angels were created before Adam and Eve, and there is no record of any angel dying, even from the war that broke out due to their defiance. Sinning angels, at least 6,000 years old, continue to exist, with no indication in Scripture of new angels being created. Though their movements are restricted to the earth unless called before God, they remain free to deceive and harass mankind to some extent. The penalty for their sins has not been fully carried out beyond a measure of constraint, leaving open the question of whether further judgment awaits. These sinning angels express fear of destruction and torment, acknowledging a set future time for their reckoning, yet they continue to live like prisoners with no hope of parole. Scripture indicates that the wages of sin, if not repented of, is death, and an angel, as a living being with the liberty to make moral choices, is also a soul subject to this principle. God's justice is fair, using the same standard for all, whether man or angel, with each judged individually. As God purges sin and unrepentant sinners from existence, sinning angels are not excused; their sinful works are to be burned up along with all contamination on earth. Prophecies of the New Heaven and New Earth describe a righteousness so pure that no sin, not even in memory, will remain. The unrepentant, lying, and murderous demons will not endure; they will be burned up in the Lake of Fire, ensuring that nothing will mar the pure moral and spiritual environment of God's Kingdom.
