Yes, demons are powerful, and the Bible indicates that any human being who trifles with them is entering foolish and dangerous territory (2 Peter 2:10-12; Acts 19:13-16). However, though the demons/fallen angels are enemies of God and humanity, they are defeated enemies. Satan may be the prince of this world, but greater is He who is in us than those who are in the world (Ephesians 2:2; 1 John 4:4).
demons as well as demonic spirits most certainly do exist. I have witnessed it first hand. It is very scary to see this. Also, I believe the demonic spirits can attach themselves to others given the chance.
Listen To me is this way we all want to believe things like this , but we rather see it to believe it But other than that sometimes you don't have to see it. If there's good than that's like god is real. If there's bad than there's evil
No. It's a ridiculously primitive belief supported by zero evidence. Early man invented the idea of "demons" to explain things he did not know or understand, such as psychological disorders and disease.
Revelation 12:8-9 "And the Dragon lost the battle and was forced from heaven. This great Dragon---the ancient serpent called the devil, or Satan, the one deceiving the whole world --was thrown onto the earth with all his army." (The Bibles explanation of SATAN'S origin and his activities makes clear why, despite the desire of the majority to live in peace, mankind has been plagued with hatred, violence, and war for thousands of years and why this has reached such a level that it now Threatens to destroy all mankind)
