Are there demons in our world? Yes there are. They are existing like spirits. Demons are spirit being and we cannot see them with our physical eyes. There are everywhere on earth. The Bible says that Satan answered God in the book of Job that he was coming from walking to and from on earth. Satan and his demonic forces move around on earth freely. As they are moving, they cause havocs and wickedness. We are not seeing these spirit being. They are the ones who see us. They are spirits and physical eyes cannot see spiritual things. It is the spiritual that controls the physical.
The works of darkness are manifest just as the Bible tells us. It shows up itself in all forms of wickedness and evil which is dominant in the world today. We have seen that in our world, people do not have respect for human life. Cultists and other workers of evil shed blood at will to satisfy their evil plans. Children refuse to submit to the authority of their parents because of the demonic influence stirring them to be disobedient to parents. The gospel of our Lord Jesus Christ is not accepted by many people just because the demonic forces rule their minds and blind their eyes against the truth. The existence of demons is real. We should keep ourselves by the word of God so that we can be free from their oppression.
