When we are being attacked for being a part of Christ's kingdom, we must fight with spiritual weapons. Our warfare is not against people, but against the spiritual powers that operate behind the scenes through people. We must realize who the real enemy is and fight with the spiritual weapons the Lord has given us.
We often think that anger will put a person in his place. But "the wrath of man does not work the righteousness of God" (James 1:20). Anger displayed against people puts us right into the hand of the devil. The way to overcome the spiritual powers that come against us through people is to turn the other cheek (Matthew 5:39), meaning we just smile and change the subject. That makes the demons flee in terror.
One of the main weapons the Apostle Paul speaks of is the Gospel, which is the Sword of the Spirit, (the Word of God). It's the Word backed by God's Spirit that can pull down and crush the strongholds of Satan.
Every Christian is at war. There is a continual struggle against Satan and his kingdom from which there are no "leaves" or "discharges." Our enemy goes about as a roaring lion, seeking whom he may devour (1 Peter 5:8). Those who resist the devil will see him flee (James 4:7). The only ones whom he devours are those who don't actively fight against him.
