What message did John the Baptist preach?

John the Baptist's ministry was marked by a clear and pressing message centered on the total depravity of man and the necessity of true repentance. He called the people to acknowledge their sinfulness and highlighted their need for a Savior, stating that every tree that does not bear good fruit is 'hewn down' (Luke 3:9). His baptism symbolized not just a ritual but a deep inner transformation that comes through repentance for the remission of sins. Importantly, John also heralded the coming of Christ, stating that while he baptized with water, the One coming after him would baptize with the Holy Spirit and fire (Luke 3:16), underscoring the transition from the old covenant to the new. John's preaching laid the foundational understanding of Jesus as the Messiah.
