You are Giving the Devil too much credit
You cannot underestimate the enemy. As Christians, we need to know who our enemy is. At the same breath you cannot overestimate the enemy. You can’t always blame the devil. I have a friend who loves blaming the devil. Everything that happens is of the devil.
When his tire burst – it was the demon of flat tires
When his wife is overreacting – it was the demon of overacting
When they are in an argument – it is the spirit of unforgiveness.
I think we need to be careful with how we use our words and terms. To my preacher friends, we have to think about the terminologies we use because it has its implications.
If a Christian brother who understands the gospel, has unforgiveness in his heart, he doesn’t need deliverance from the spirit/ demon of unforgiveness or bitterness. He needs to repent of his sin. He needs to live out the gospel by the power of the Holy Spirit and not give the devil too much credit. We need to point out the reason why he is unwilling to forgive if he has experienced the unconditional love and grace of God. He needs to see the idolatry in his heart why he has unforgiveness. If all we do is just cast out and rebuke the demon in him, )or personally I would use the word SIN, since all SIN is demonic) then he could end up with 7 more wicked spirits.
Thus I am saying let us be careful with the terms we use. Is it technically demonic? Yes but should the response be always casting out the demon? No, since all sin is demonic.
So the next time you are faced with situations like these, ask – does he need deliverance aka “casting out of demons” or repentance?
