What does the Bible say about the purpose of Jesus' ministry?

In Luke 4:18-19, Jesus declares His purpose, saying, 'The Spirit of the Lord is upon me because he hath anointed me to preach the gospel to the poor; he hath sent me to heal the brokenhearted, to preach deliverance to the captives, and recovering of sight to the blind, to set at liberty them that are bruised, to preach the acceptable year of the Lord.' This mission highlights His role as the Savior who brings true hope and deliverance, particularly to those who recognize their spiritual poverty and brokenness. His proclamation signifies the onset of a new era of grace and salvation initiated through His person and work.
