What makes a person successful in spiritual warfare?

In spiritual warfare you have to remember that you wrestle not with flesh and blood. You are fighting evil spirits, therefore you need to be prepared to fight the way they fight...through actions. They can't do anything without your permission.

First, you must have endurance (2 Timothy 2:3) - the ability to endure and withstand hardship, adversity, or stress. We are to endure hardness as a good soldier of Jesus Christ.

Second, you must have hatred for the devil (Psalms 139.22) - extreme dislike or antipathy, loathing. In spiritual warfare, we must have a hatred of evil spirits.

Third, you must have knowledge (2 Corinthians 2:11) - we are not to be ignorant of Satan's devices.

Fourth, you must have persistence (Psalms 18:37) - the ability to go on resolutely or stubbornly in spite of oppression. We must be persistent in dealing with the enemy.

Lastly, you must practice separation (2 Timothy 2:14) - to get or keep apart. No man who wars entangles himself with the affairs of this life.

God uses ordinary people to accomplish His purposes. Our ability comes through grace. Every believer is sitting in heavenly places in Christ. Your position in Christ is high above all principality and power. You must see who you are in Christ. You can do all things through Christ.
