What does the Bible say about fear and anxiety?

In Luke 12:22-30, Jesus addresses fear and anxiety directly, urging His followers not to be consumed by worries about daily needs like food and clothing. Instead, He reassures them that God, as their Father, knows what they need and provides for them. This passage emphasizes that life is more than material sustenance and calls believers to trust in God's sovereignty and care, illustrated by His provision for the birds and the flowers. Christians are reminded that their priority should be to seek the kingdom of God, and all these other needs will be taken care of.
