Anxiety is a spirit that gladly takes its legal right once YOU'VE given it access. The manifestations/symptoms (fruit) are real and clinical (see diagnostic manual: DSM-5-TR).
As a Christian, I believe that the fruit we experience is as a result of being out of alignment with God either through disobedience or rebellion. See The Book of Deuteronomy for teachings on blessings and curses among other things. Drawing close to God invites His blessings—closeness invites Him (James 4:8). Moving away from Him invites the consequences (curses) embedded in each act of sin (falling short of His standard intentionally or by mistake).
"Anxiety is to be repented of" (God to Bobby Conner).
Why is Repentance the Method Here?
In Philippians 4:6 we are told: "Be anxious for nothing..." If you are experiencing the manifestations, symptoms, fruit, of anxiety, we can then conclude that you're in direct disobedience to what God has instructed you to NOT do. Again, "be anxious for nothing..."
The How...
The only way to engage anxiety as a Christian is to realign with God through His Word that instructs us this way: "...but in everything by prayer and supplication (humbly approacing God), with thanksgiving, let your requests be made known to God; 7 and the peace of God, which surpasses all understanding, will guard your hearts and minds through Christ Jesus (Philippians 4:6-7 NKJV).
Your request is to be free and to stay free from anxiety. I believe as you ask God in sincerity, He will answer. It is you who has to believe He has answered. How can you know He has answered? The peace of God will become a guard (an impenetrable barrier against invasion) for your hearts and minds (places where Satan enjoys to attack God's children) through Christ Jesus (our Only Savior).
Ask God (Prayer/Your Request)...
"Father in Jesus' name, I thank You that You even care for me, that You sent Jesus to die for me. I thank You that You are Good. I come to You because I believe You can set me free. I want to be free from anxiety. I am sorry for anything I did to give the enemy legal right to torment me. Father, I come out of agreement with any actions or lies I have believed that have caused there to be an open door in my life to the enemy. I close that door now in the name of Jesus, and I give You permission to be my Lord and Savior. Please help me. Amen."
This prayer is you submitting to God. Your prayer doesn't have to be mine, it can be any variation that is placed on your heart as you speak to God. As you then resist the devil (speak God's Word with authority). Below are some helpful verses to reinforce your freedom:
John 8:36
2 Corinthians 10:5
Genesis 3:15
Revelation 12:11
Philippians 4:13
As humans, we tend to appreciate less what is given to us. For some reason, we often appreciate more when we've personally worked for something. For this reason, I am asking that you add work to your faith here and your desire to have true freedom in Christ, by searching out the Scripture for yourself and engaging these verses so they can mean something to YOU personally. Spend YOUR own time with Jesus to know what His Word means.
Satan MUST Flee.
The Word of God against him is stronger than he is. Any act from him after God has decided on a matter in your favor is an act of aggression against the Kingdom of God to which you belong. When satan tried to fight for Moses' body, not only was his effort useless, but he was also met with the force of the Arch Angel Michael who said: "the Lord rebuke you (Jude 1:9)." GOD had already decided on the matter and there was nothing Satan could've done to change that. See Zechariah 3 for an Old Testament reference. God's Word is final and to It, every knee shall bow and every tongue in heaven, earth, and below, must confess that Jesus Christ (God's Word) is LORD, to the glory of God the Father (Philippians 2:10-11).
Believe You've Been Forgiven...
Your act of repentance is what 1 John 1:9 NLT speaks of: "But if we confess our sins to Him, He is faithful and just to forgive us our sins and to cleanse us from all wickedness."
Receive it...
Welcome His love and forgiveness into your heart. Speak this confession out loud. Ask for His strength to continue to walk His path and not the one from which you just repented (changed directions in thought or action).
Final thoughts...
If you're not a Christian, this method is obviously not for you as you don't believe.
If you call yourself a Christian but are skeptical, choose faith and watch God free you as well.
Take a deep breath. Give God thanks. Enjoy your new freedom by staying free. It is important that I mention that there is a difference between acknowledging that something may be off with you and agreeing with satan's will for your life. Acknowledge the problem to find a solution, not wallow in self-pity. You CAN do all things through Christ Who infuses you with inner strength (Philippians 4:13)—you will get through this. Don't agree with the enemy's will for your life through the negative words you speak over your situation or actions you take or do not take.
