This sermon unpacks the opening of Mark’s Gospel, showing how John the Baptist prepared the way for Jesus as foretold by the prophets. At His baptism, Jesus is revealed as God’s beloved Son, empowered by the Spirit, and set on a mission that would lead to the cross and victory over sin and Satan. The preacher emphasizes the urgency of repentance and belief, reminding us that the gospel is the true good news and the only hope for salvation. Christianity is not partial commitment but a call to make Christ the central authority and organizing principle of our lives. The message concludes with a clear challenge: today is the time to repent, believe, and live under the kingship of Jesus.
