What does the Bible say about worry?

Scripture presents clear arguments against worry, particularly in Luke 12:22-31, where Jesus encourages His followers to consider the ravens and lilies. Ravens do not sow or reap, yet God feeds them; lilies do not toil or spin, yet they are more splendid than Solomon. These illustrations highlight God's provision and care, leading us to understand that if He cares for the birds and flowers, He will surely provide for His spiritual children. The passage also emphasizes that worry is characteristic of those who do not know God, while believers are implored to trust in their Heavenly Father’s perfect knowledge of their needs. Ultimately, worry undermines peace and usefulness in a believer's life, while trust in God glorifies Him.
