I have an interesting story for you....
Driving to Qld, on the second day of our drive, it started to rain. That's fine. No one minds the rain, but it got heavier and heavier and I decided; you know what? This is a seven-hour drive. It can rain behind me. I want a dry run.
So, I decreed "shalom" which means a lot of things; one being from ancient Hebrew, meaning anarchy and chaos leave, peace come.
"Rain cease. Peace. Be still."
I heard the devil say; "Who do you think you are (to command the rain to stop)?"
I replied; "I know who I am and so do you."
The devil left, the rain stopped and it was dry the rest of the trip.
Have you ever asked God to tell you your identity? You can ask Him and He will reply.
When I asked, God told me; l am a tenacious woman, a woman of a gentle and quiet spirit. I can agree with that.
However, that's not what I told the devil. When he asked who do I think I am, I told him; “I am a pillar in the temple of the Lord, a righteous child of the Most-High God, a King and Priest in the Order of Melchizedek. Greater things will I do, for He has gone to the Father. He (Jesus) gave me ALL authority and you (satan) have no legal standing (for I have nothing in him).”
So, the rain stopped (because it's true - greater is He that's in me) and then we picked up dirty fuel and I knew the devil was trying a different tactic.
We think we picked up some dirty fuel as the ute began to miss and chug after filling the tank. It was chewing through the juice too. We had to fuel up a second time a few hours later, we'd gone through so much fuel and when we did, everything returned to normal. Dirty fuel was all we could think of but my thoughts at the time were on the devil's tactics.
There's a bible verse I quote when this kind of thing happens. Job 5:22 “I laugh at disaster and famine and I will not fear the beasts of the field...” (after all, isn't the devil just another beast?) I was quoting this verse, and at the same time, speaking in tongues while endeavouring to remain calm in a trying situation. At the end of the day, no calamity struck.
You see, we can all walk in power because it's a gift from God. We can pray for healing, pray for provision and pray for favour. The power of God works in us. We can't all cast out demons, however, or stop their attacks. That's a higher level of warfare and it takes greater authority to do so.
Authority is a different matter to power. If you want authority, the kind of authority that casts out demons, that only comes through relationship with God; through fasting and prayer, and just good old, plain old, conversations with God - sitting and chatting with Him.
It's powerful stuff.
And a little additional information here...
Adam and Eve lost their authority after eating the forbidden fruit and satan gained the authority they lost. Jesus won it back.
Satan lost that authority when Jesus went to hell and took that authority back from satan. He then gave us that authority and we can walk in it, it's my understanding, if we spend time with God.
The bible speaks of the seven sons of Sceva who were stripped and scratched and thrown to the ground. Satan said; "Jesus I know and Paul I know, but who are you?" The demon then turned on them viciously.
Acts 19:13-16 ...Then the man in whom the evil spirit was leaped on them, and prevailed against them, so that they fled out of that house naked and wounded.
The demon-possessed man jumped on them and overpowered them all. He gave them such a beating that they ran out of the house naked and bleeding.
The seven sons didn't have a relationship with Jesus. They were trying to emulate Him but without knowing Him personally, they failed miserably.
So, keep doing what's right, staying in right standing with Jesus. Spend time with God and we shall overcome the enemy in every area of our life.
