The Importance of a Baptism by Water

Isaiah, chapter 40, gets quoted in the story of John as he prepares for Jesus to be baptized. And Isaiah 40 is this significant turning point in the book of Isaiah where hope is the theme. So here's John preaching out here in the wilderness. And he's telling the people, verse 8, I indeed have baptized you with water, but he shall baptize you with the Holy Ghost. This person who's coming after me, who's mightier than me, he's going to baptizeYou with fire.
