Here are some simple principles of Spiritual Combat: Humility is the key: Satan tried to raise himself to the equal of God. When we strive after true humility we place our selves in the complete and total control and protection of our Father. The Father will protect us when we root pride out of our lives. Satan despises the virtue of humility because it is the opposite of him. When you decide to enter into the spiritual battle first clothe yourself with humility as it will hide you and protect from the plans of the evil one.
The primary battle is in our own lives: Spiritual warfare does not mean only deliverance ministry although sometimes we will be praying for deliverance of others from evil spirits. Spiritual warfare is first and foremost the battle against sin in our life. If you have thoughts of combating the devil then first see how the evil one is working in your life and fight him there. The greatest thing we can do to combat the devil is to become a saint.
Remember Satan is the Father of lies: Again I must go back to the virtue of humility. Satan is the master deceiver but when we clothe ourselves with the eyes of humility we see ourselves and the world in truth. Be bold only in the power of the Lord and not in yourself. Take care to live in the Truth and not be deceived.
The battle is the Lord’s!
The prayer to St. Michael can be a powerful weapon in our Spiritual armament. Here is a copy of the original text:
Prayer to St. Michael the Archangel
Most glorious Prince of the Heavenly Armies, Saint Michael the Archangel, defend us in “our battle against principalities and powers, against the rulers of this world of darkness, against the spirits of wickedness in the high places” (Eph., 6,12). Come to the assistance of men whom God has created to His likeness and whom He has redeemed at a great price from the tyranny of the devil. Holy Church venerates thee as her guardian and protector; to thee, the Lord has entrusted the souls of the redeemed to be led into heaven. Pray therefore the God of Peace to crush Satan beneath our feet, that he may no longer retain men captive and do injury to the Church. Offer our prayers to the Most High, that without delay they may draw His mercy down upon us; take hold of “the dragon, the old serpent, which is the devil and Satan”, bind him and cast him into the bottomless pit … “that he may no longer seduce the nations” (Apoc. 20, 2-3).
