Kingdom, Judgement and Why This is Good News - Matthew 3

In Jesus, the kingdom of heaven is here. Jesus has come to identify with his people and invites us to participate in this brand new reality, the kingdom of heaven. 

As John the Baptist comes onto the scene, John is preparing for King Jesus and proclaiming that God's kingdom is here. As God's kingdom is breaking into this earth, God is going to deal with evil and sin. The call is to repent and turn to King Jesus and his vision of life. But in the midst of Matthew 3, the subject of God's wrath and unquenchable fire come up. How does that factor in? How is this good news?
