A peaceful life is impossible without confidence in the Lord. That trust is built through a relationship with Him-praying through trials and triumphs, seeking His guidance, and testing His Word to see that it is true and practical for life.
When we’ve experienced God’s faithfulness and believe He will continue to act on behalf of His followers (Isaiah 64:4), that’s when peace is possible. In fact, it is not only possible but promised to the believer who trusts in Him (Philippians 4:6-7). But unshakable peace isn’t instantaneous; it is cultivated through a consistent relationship with the Lord.
