Jesus and the apostles cast out demons on what seems like a regular basis. Demons were apparently quite common.
Have the demons died?
Are they locked away?
Demons are fallen angels. They are beings of great power. The activities of these demons in the days of Jesus were normal for them. Satan and his fellow fallen angels were trying to undo the things God has done and will do in the future. That hasn't stopped just because a couple thousand years have passed. What is a thousand years to an immortal angel?
Why, then, do we not see more evidence of demonic activity and possession?
Satan is called the father of lies for good reason. We don't see these things because we are not looking for them. Satan has so deceived the world that even we who call ourselves Christians rarely ever perceive the supernatural. When we do stumble upon it, we tend to disbelieve the true cause.
Satan is very intelligent. He knows how to trick us and is very good at it. I am sure we all walk right by demons every day and have no idea. In some ways primitive cultures have an advantage here because they know, they Know, that there is more to this life than what they can see.
Pray for eyes to see and the wisdom to discern the plots of the evil one. Pray for protection because we are always walking into an ambush.
" Finally, be strong in the Lord and in the strength of His might. Put on the full armor of God, so that you will be able to stand firm against the schemes of the devil. For our struggle is not against flesh and blood, but against the rulers, against the powers, against the world forces of this darkness, against the spiritual forces of wickedness in the heavenly places. Therefore, take up the full armor of God, so that you will be able to resist in the evil day, and having done everything, to stand firm."
Ephesians 6:10-13
Maranatha!
Come Lord Jesus!
