Philippians 4:6-7
6 Do not be anxious about anything, but in everything, by prayer and petition 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 your minds in Christ Jesus.
2 Timothy 1:7
For God has not given us the spirit of fear; but of power, and of love, and of a sound mind.
1 Peter 5:6-8
6 Humble yourselves therefore under the mighty hand of God, that he may exalt you in due time; 7 casting all your worries on him, because He cares for you. 8 Be sober, be vigilant; because your adversary the devil walks about like a roaring lion, seeking whom he may devour.
God knows and sees all. If you are remaining humble before Him, then you won't have to explain to Him why you are worrying when He is there to be your comfort. Recognize that you are being tempted in your thoughts to worry and then you must battle to resist that temptation. Because when you start worrying, you go outside of God's will. Nevertheless, you don't do that intentionally. But recognize that it's God's place in your heart and all that He represents that is being attacked so that in the end God is misrepresented to you. And for a moment you are not seeing Him as your high tower and your refuge (Psalm 18:2).
Psalm 27:1
The LORD is my light and my salvation. Whom shall I fear? The LORD is the stronghold of my life. Of whom shall I be afraid?
David may have dealt with people harassing him, but you are fighting a spiritual war and spiritual entities do come against you. They come in the form of thoughts and worldly concerns. So, your confession of faith could sound like this: "The LORD is my light and my salvation. What shall I fear? The LORD is the stronghold of my life. Of what shall I be afraid?"
The worrying is an action that takes your consent and participation. So, you have to instead resist the urge to do that when you are being tempted (James 1:12). Tell God that you are on board with his will and that you submit to the fact that He is the one in control of all that happens in or around your life. Ask Him for strength to stick to the choices you have made to do what is pleasing to Him and cast to Him all your burdens (1 Peter 5:7). He has only called you to bear the burdens He knows you can carry with his help. And if you are seeking God's kingdom first in your life (Matthew 6:33), then by his grace, you need to stand in that place where you have peace that God is leading you through the best path for your life according to his perfect will, regardless of how the circumstances that surround you look to you. When you are there and content, the worrying won't really make sense. But you have to battle your way to that place of peace as you keep your focus on God and put your life in his hands in total submission to Him.
And for as long as you are being attacked in your thoughts by the devil who wants to steal your peace, and that you keep on finding yourself worrying (despite disagreeing with those thoughts and not welcoming them), you need to confess your worrying to God; and you need to resolve in your heart to not continue worrying. It's a spiritual war. So, be alert and aware that something is coming to eliminate your assurance in God's care and therefore make you not see God as who He is to you. It is a good instance to use memorized scriptures as a weapon.
You are dealing with a mountain and all you need is your faith to cast it into the sea (Mark 11:23). Endure in your fight with Jesus who strengthens you (Philippians 4:13). And by faith, you need to see the day of your deliverance, where you will look back and realize you haven't been having these kinds of disruptive thoughts, and give all praise to God!
God be with you!
