Malachi, the last prophet of the Old Testament, delivered a message of both warning and hope to the people of Israel. He called them to repentance, exposing their half-hearted worship and corruption, and warned of a coming day of judgment for the wicked. However, Malachi also promised a future of healing and restoration for those who fear and honor God, proclaiming that the "Sun of Righteousness" would rise with healing in its wings. This prophecy pointed forward to the coming Messiah, Jesus, who would bring spiritual healing and renewal to God's people.
