What does the Bible say about anxiety and worry?

In Luke 12:22-24, Jesus instructs His disciples not to be anxious about their lives, including what they will eat or wear, because life is more than these physical concerns. He uses the example of ravens, which do not sow or reap yet are fed by God, to illustrate His sovereign provision for all creation. This passage emphasizes that believers are of greater value than birds, and therefore, God will provide for their needs according to His perfect will and timing. Trust in God's providence is a foundational aspect of the Christian life, reminding us that He cares for us in every situation.
