What the Holy Bible says about Anxiety / Fear / Worry:

Do not be anxious about anything, but in every situation, by prayer and petition, with thanksgiving, present your requests to God. And the peace of God, which transcends all understanding, will guard your hearts and your minds in Christ Jesus. (Philippians 4: 6-7)

Cast all your anxiety on him because he cares for you. (1 Peter 5: 7)

For God has not given us a spirit of fear, but of power and of love and of a sound mind. (2 Timothy 1: 7) (NKJV)

15 For you did not receive the spirit of bondage again to fear, but you received the Spirit of adoption by whom we cry out, “Abba, Father.” (Romans 8: 15) (NKJV)

38 For I am convinced that neither death nor life, neither angels nor demons, neither the present nor the future, nor any powers, 39 neither height nor depth, nor anything else in all creation, will be able to separate us from the love of God that is in Christ Jesus our Lord. (Romans 8: 38-39)

13 I can do all things through Christ who strengthens me. (Philippians 4: 13) (NKJV)

10 So do not fear, for I am with you; do not be dismayed, for I am your God. I will strengthen you and help you; I will uphold you with my righteous right hand. (Isaiah 41: 10)

25 “Therefore I tell you, do not worry about your life, what you will eat or drink; or about your body, what you will wear. Is not life more than food, and the body more than clothes? 26 Look at the birds of the air; they do not sow or reap or store away in barns, and yet your heavenly Father feeds them. Are you not much more valuable than they? 27 Can any one of you by worrying add a single hour to your life? 28 “And why do you worry about clothes? See how the flowers of the field grow. They do not labor or spin. 29 Yet I tell you that not even Solomon in all his splendor was dressed like one of these. 30 If that is how God clothes the grass of the field, which is here today and tomorrow is thrown into the fire, will he not much more clothe you—you of little faith? 31 So do not worry, saying, ‘What shall we eat?’ or ‘What shall we drink?’ or ‘What shall we wear?’ 32 For the pagans run after all these things, and your heavenly Father knows that you need them. 33 But seek first his kingdom and his righteousness, and all these things will be given to you as well. 34 Therefore do not worry about tomorrow, for tomorrow will worry about itself. Each day has enough trouble of its own. (Matthew 6: 25-34)

27 Peace I leave with you; my peace I give you. I do not give to you as the world gives. Do not let your hearts be troubled and do not be afraid. (John 14: 27)

I sought the Lord, and he heard me, and delivered me from all my fears. (Psalm 34: 4) (KJV)

28 Do not be afraid of those who kill the body but cannot kill the soul. Rather, be afraid of the One who can destroy both soul and body in hell. (Matthew 10: 28)

Keep your lives free from the love of money and be content with what you have, because God has said, “Never will I leave you; never will I forsake you.” So we say with confidence, “The Lord is my helper; I will not be afraid. What can mere mortals do to me?”  (Hebrews 13: 5-6)

God is our refuge and strength, an ever-present help in trouble. Therefore we will not fear, though the earth give way and the mountains fall into the heart of the sea, though its waters roar and foam and the mountains quake with their surging.There is a river whose streams make glad the city of God, the holy place where the Most High dwells. God is within her, she will not fall; God will help her at break of day. Nations are in uproar, kingdoms fall; he lifts his voice, the earth melts. (Psalm 46: 1-6)

The Lord is with me; I will not be afraid. What can mere mortals do to me? (Psalm 118: 6)

14 But even if you should suffer for what is right, you are blessed. “Do not fear their threats; do not be frightened.” (1 Peter 3: 14)
