Recognize that your fight is not with flesh and blood but with the powers of darkness and Satan’s spiritual rulers of this age. This age (world)has become the battleground between these satanic forces and humankind. Therefore, you are not fighting against people you know or with whom you come in contact in your daily life. Instead, the enemy may harass you by stirring up strife in the lives of people close to you to deter you from prayer and intercessional battle.
To bind the strong man; You must first know who the strongman is. It can be a principality, power, ruler of darkness in this world, or spiritual wickedness in high places Eph. 6:12. This is discerned through prayer and must always be within the will and timing of God. Many times fasting must accompany that prayer. When the man asked Jesus why His disciples could not cast the demon out of his son, He replied, “But this kind does not go out except by prayer and fasting.” Matt 17:14-21.
Every believer has the right and authority to call down or resist the devil and bind the strong man. You, as an individual, will be singled out and challenged by the spirits of darkness. Or you will be called into war against the powers over your home, Church, city, etc. Binding and loosing demonic spirits or powers of higher-level spiritual dominion is definitely something you do not want to do without knowing what you are doing. When calling down strongholds, you may assist another in prayer and agreement as you learn, but never work alone. You must know your spiritual jurisdiction.
