Think of spiritual warfare in the same sense as you would a physical war. The enemy hates you and wants to do all he can to steal, kill and destroy. John 10:10. This is serious business and we have to know what to do when he attacks, because he will try to! I will list the defenive weapons, offensive weapons, what it protects, how to keep each weapon in tact and how the enemy may try to attack that weapon.
Our Defensive Weapons
1.) Helmet of Salvation - In the spiritual realm, the helmet of salvation is given to all those who are saved because of Jesus Christ's sacrafice to pay for their sins.
What it protects - The helmet of salvation protects your thoughts in the spiritual realm. I know that you guys have heard of people knowing what other people think or reading someone else's thoughts and I believe this is possible when someone doesn't have a helmet of salvation. I believe that the helmet of salvation makes it harder and more difficult for the enemy to attack your mind because it serves as a buffer in the spiritual realm.
How to keep it in tact - Watch what you ingest through your ears and eye gate because these are the gates that are used to get to your mind. So many Christian men are struggling with pornography because the devil is using the ear and eye gate to attack their mind. He knows that as a man thinketh, so is he. So, watch what you are thinking and use the Word to counterattack the enemy by casting down thoughts...2 Corinthians 10:5.
How the devil will try and attack it - Overtly sexual, extremely violent, witch craft themes in movies, bill boards, television programs, music, internet articles, threads and forums, etc.
What Happens If You Don't Protect It - In the spiritual realm, I can imagine that when a person has allowed certain things to come against their mind, there may be cracks in their helmet. There may be a young Christian woman that is having trouble with thoughts of fornication and without checking them and casting them down, those thoughts turned into actions. Every action first started with a thought, so if something is too hard for you...seek understanding and humbly come to God and ask Him to help and He will!
