Question: where in the bible does it mention worry?
Answer: Proverbs 12:25 Anxiety in a man's heart weighs him down, but a good word makes him glad. 1 Peter 5:7 Cast all your anxiety on him because he cares for you. Philippians 4:6-7 do not be anxious about anything, but in everything by prayer and supplication with thanksgiving let your requests be made known to God.
