Matthew 6:25-27,34
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 important than food, and the body more important than clothes? 26Look 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? 27Who of you by worrying can add a single hour to his life? 34Therefore do not worry about tomorrow, for tomorrow will worry about itself. Each day has enough trouble of its own."
John 14:1
1"Do not let your hearts be troubled. Trust in God; trust also in me."
Isaiah 40:31
31 but those who hope in the LORD will renew their strength. They will soar on wings like eagles; they will run and not grow weary, they will walk and not be faint.
1 Peter 5:7
7Cast all your anxiety on him because he cares for you.
