I want to add something about the world we live in and spiritual warfare. It might seem a little freaky, but it is a reality. One only has to look at the scriptures to see that it is. Some think that this all passed away when the apostles died out, but everything remains as it was following the resurrection of Jesus and the sending of the Holy Spirit baptism.
All around us is a spirit "realm". We are three part beings. We are a spirit with a soul and have a body. Your spirit and soul are tied to this body. When we die, we go to the kingdom we belong to. It is your tie to this physical realm, that the enemy uses to try and get into "your gates".
There are 2 kingdoms. In the spirit realm, we have both angels and devils all around us. Thank God we can't see them (typically)! Our perception of life on this planet would be pretty different and we would know that we're never alone. But God gives those who are sensitive to His Spirit an awareness or "discernment" to assist you in your walk by faith (not by sight).
As a believer you are a partaker of the victory He won for us at Calvary. The enemy even though he is defeated, is a thief and a destroyer, and he will keep you in as much bondage as he can. We sometimes give them a legal right to afflict us. The rules are all in God's Word. They quote the Word to God (who knows He hears) and they seize the opportunity to oppress you. God permits many things to happen that are totally against His will. He does this because He will not violate His Word.
It is up to us now to find out what God expects and what keeps the enemy defeated (so we can have a glorious walk in peace). You won't have much of a supernatural walk if you don't make this your very aim in life. God kind of "woo's" you at first. He stands around you and protects you. The enemy will take every shot he can give you. If you go around getting high or buzzed on beer, you'll have given him access to your soul. The next day you regret it, go to church, etc., but as bad as you feel, you are in bondage. Until you are released by repentance and the move of God's Spirit, you are a prisoner.
If you give your soul to watching movies or TV shows where they break the commandments of God, you are watching the enemy's entertainment. He'll come in and afflict your soul. You can forsake your own mercy by observing "lying vanities".
It's not about just giving stuff up. God's kingdom is more exciting than anything the devil has to offer. You have to learn to press in and receive from God actively. You have to learn His ways. Learn to flow with the wind of the Spirit of God and know Him. We are told we can know God intimately and new believers must come away and out from "her" (the ex-wife) and become "wed" (living that way) to your new husband, Jesus Christ!
All of those things mentioned in Hebrews 6 can be experienced personally. Being born again, filled with the Holy Spirit, feeding on the good Word of God (not just mentally but in a life changing "leavening" of your inner man), moving in the powers of the world to come (Heaven). This is the supernatural walk of the Spirit. If you hear this in your spirit man, you can forsake the "treasures" of the world and begin to press into God for the "hidden treasure in the field, the parable speaks of). You'll sell everything you have to get it. You'll end up considering what you gave up as absolute "DUNG". You can be free of the bondage to sin and have not only peace of mind, but great piece of heart and supernatural love.
It starts as a very small seed, but you have must faith in what that seed reproduces and get rid of everything that opposes your new life. You must fellowship with those who are like minded and forsake the things of old.
