One of the very ways the enemy gets in our head is allowing his thoughts to be ours. What do I mean by that...if you had a deed to land that is yours and you allow a person to have "squatter's rights" when they do not legally own the land, then you are giving them permission to freely occupy and own your land. Your mind is your land.
The enemy will play games with your mind just as the narcissists of this world want you to forfeit possession of your mind. They want to take the control away from you and keep it for themselves so they can wreak havoc in your life.
These evil beings whether human or demonic begin telling you that your worth is a fraction of what you thought it was. They will negotiate your very right to exist beginning with your self worth. If you give the enemy the right to steal, kill and destroy you then you have negotiated down your worth by your own merit.
Let's say you own a house and it is paid for. Would you give your house key to a stranger who says I want your house, give it to me! Then when the key is handed over they go in like a tornado and demolish everything in sight just for the fun of it. Will they ever sincerely apologize? No,they will scold you because you gave them the key in the first place and it was your fault for doing so. Don't give the devil the key to your life to come in and ransack your emotions, mind, body and soul.
10 The thief cometh not, but for to steal, and to kill, and to destroy: I am come that they might have life, and that they might have it more abundantly.
11 I am the good shepherd: the good shepherd giveth his life for the sheep.
But the enemy is a lot more subtle and manipulative than that... just as the narcissist.
Narcissists like to whittle you down by letting you know how insignificant your life is, how you will never measure up to their expectations while they raise the bar each time. This game is meant to solidify that you are a failure and they the successful and flawless human being that is never tainted with inferior DNA cells.
NPD's consistently point out construed and bogus manufactured deficiencies of your pitiful self as if you were Al Capone of the century, the notorious mobster man.
The drama whirls into a thoroughly constructed battle though they do not warn you as they believe you are the pathetic martyr who will never win at their game of decimation.
They will wait for your reaction and defense to only smirk at your emotional response as if to say, I have you in the palm of my hand. Their grandiose prize...watching the pain throb in your heart and the tears in your eyes, better than a stuffed animal at the fair.
This game of manipulation is a way of compromising who you are as a person to conform to who they want you to be...their slave in misery, bound in chains of affliction.
When you give up your mind, you are giving your soul a slow death. You don't realize you are being drained of every ounce of life because they give reasons why your cup should be empty, you don't deserve a cup that is full or overflowing.
The power to obtain happiness cannot be under your dominion or even God's because they believe they have rightful ownership to hijack, plunder and make spoil of your entire life. They consider you a type of rubbish that is useful for composting time and time again.
So my point is, the moment you allow this evil to have squatter's rights, you have handed your deed over willingly and the rest will manifest in your personal torment, self worth and misery. You have a key to your soul and mind that should never be given over to evil perpetrators who will ravage what God deems valuable in His sight. Which is you! God sent His Son Jesus to die for you. Don't let the enemy blaspheme God by robbing you of your worth.
This is why it is crucial to have control over your thoughts and actions. God has given us self control and power through His Holy Spirit.
2 Timothy 1:7 (KJV)
7 For God hath not given us the spirit of fear; but of power, and of love, and of a sound mind
God says we have the mind of Christ.
(I Corinthians 2:16)
Would Jesus allow the enemy to enter His thoughts, No!
There are many avenues that "evil squatters" will attempt their invasion so as Ephesians says you must put on the armor of God.
Don't allow yourself to be tricked, duped, deceived or defrauded. Don't take the bait otherwise oppression will be knocking on your door...the key please.
10 Finally, my brethren, be strong in the Lord, and in the power of his might.
11 Put on the whole armour of God, that ye may be able to stand against the wiles of the devil.
12 For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places.
13 Wherefore take unto you the whole armour of God, that ye may be able to withstand in the evil day, and having done all, to stand.
1 Peter 5:8-9 (KJV)
8 Be sober, be vigilant; because your adversary the devil, as a roaring lion, walketh about, seeking whom he may devour:
9 Whom resist stedfast in the faith, knowing that the same afflictions are accomplished in your brethren that are in the world.
Psalm 12:5 For the oppression of the poor, for the sighing of the needy, now will I arise, saith the Lord; I will set him in safety from him that puffeth at him.
