When John the Baptist addresses his congregation as a "Brood of vipers," it hardly seems like good news. Rather than an insult, however, John is calling out the misguided notion that we can avoid judgment because we're the right kind of people. We shall all be shaped for life in the reign of God through judgment or repentance. Repentance invites us to live in the presence of Christ now as people dedicated to justice, love, and compassion. It is very good news, indeed.
