As Christians, we can be sure of the existence of Satan and demons because the Bible plainly depicts them as fallen angels who work in the world to oppose God and his people, and deceive and blind unbelievers to the truth of the gospel.
We have a very real adversary today who roams around like a roaring lion seeking someone to devour. I must express that Our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms.
The Devil is bent on destroying Christians and their testimony, and stopping the progress of the gospel.
Satan does not want people rescued out of darkness and brought into the light. He will use ordinary, frustrating events to harass the believer, and occasionally he will employ extraordinary means to bolster his scare tactics.
Satan, demons, and their power are real, but they are not allowed to toy with us, even though that is what it feels like sometimes. The Devil is only permitted to do what God has decreed.
Our ultimate victory over Satan is guaranteed because our life is hidden in Christ, and he has already conquered all evil through his death and resurrection.
The Holy Spirit, who indwells believers, is the down payment on our eternal inheritance. Since the coming of the Holy Spirit, the enemy can only harass, and he certainly cannot possess believers. Amen
