John the Baptist's Ministry (Luke 3:1-6): The chapter opens with a historical setting, mentioning key political and religious figures. Then, John the Baptist begins his ministry, preaching repentance and baptizing people for the forgiveness of sins. He quotes from the book of Isaiah, preparing the way for the Lord.
