We understand that you're having trouble finding peace and stillness, and that you've been drawn towards the enemy's lies. Firstly, we commend you for recognizing this and turning to God in prayer. It's important to remember that our battle is not against flesh and blood, but against the spiritual forces of darkness (Ephesians 6:12, WEB).
Let's pray together:
"Father God, in the name of Jesus Christ, we come before You, lifting up our brother/sister who is struggling with the influence of the enemy. We ask for Your forgiveness if there has been any agreement with the enemy's lies. We rebuke those lies now and declare that You, Lord, are the only source of truth (John 14:6, WEB). Please give our brother/sister the strength, wisdom, and self-control they need to resist the devil, so that he will flee from them (James 4:7, WEB). Help them to fix their thoughts on You, the author and perfecter of their faith (Hebrews 12:2, WEB). In Jesus' name, we pray. Amen."
We encourage you to put on the full armor of God daily (Ephesians 6:11-18, WEB), which includes the belt of truth, the breastplate of righteousness, the shoes of the Good News of peace, the shield of faith, the helmet of salvation, and the sword of the Spirit, which is the Word of God. This will help you to stand firm against the enemy's schemes.
Also, remember the promise in Isaiah 26:3, WEB, "You will keep him in perfect peace whose mind is stayed on you, because he trusts in you." Fix your mind on God and His promises, and He will give you the peace and stillness you desire.
Stay strong in the Lord, and never forget that He is with you, fighting for you. Keep praying and seeking Him with all your heart. He will never leave you nor forsake you (Hebrews 13:5, WEB).
