Spiritual warfare is part of my daily routine. The world is under the control of the evil one (1 John 5:19). So we need to ensure that we are attacking the right target. We have the authority to bind Satan's evil host. We have the power to drive out demons.
My wife is especially diligent with this. She won't go into a shopping centre without binding demons first.
Believers are God's "police force". We have been given the power and authority to enforce the victory that Lord Jesus has already won. But like a cop watching a robbery and doing nothing, if we do not exercise that authority, it is useless.
As an example, I see Islam as the direct opposition to God's kingdom. The Kingdom of God should be established all over the world. Islam is Satan's attempt to thwart that. To those who are indifferent, look at the way believers are treated in Pakistan or Afghanistan. "Can't happen here," you say. In fact, it is happening. Some nations refuse to accept Islam. Funnily enough, it is nations that are have no Christian heritage. China and Japan are the main examples.
So I pray against the wicked spirit of Islam daily. I ask God to destroy Islam as one of Satan's works. I do not curse Muslims. Their dead religion is self inflicted punishment.
Individually, we need to see that temptation is not sin. We do not have to give in. We also need to realise that Satan has access to our minds and that not every thought we have is of us or from God. (2 Corinthians 10: 3-6)
This is only a most superficial look at spiritual warfare. If you want to know more, I suggest Jesse Penn-Lewis, "War on the Saints".
Thank you for reminding me of these things.
