In this sermon, the preacher emphasizes the three things that are missing in modern preaching: immensity, intensity, and eternity. He believes that if a sermon does not touch on eternity or evoke a sense of awe and reverence, it is not effective. The preacher also discusses the importance of repentance and the baptism of the Holy Spirit and fire. He uses biblical references, such as John the Baptist's preaching and the story of Solomon's altar, to illustrate his points. The sermon concludes with a call for personal transformation and a plea for God's fire to fall upon the congregation.

In this sermon, John is described as a voice crying in the wilderness, preparing the way for God. The analogy is made to the preparations made for a king's visit, where mountains are leveled and valleys filled to ensure a clear view of the king's procession. John's role is to make sure people have a clear view of the coming king, Jesus. Jesus is introduced as the Lamb of God who takes away the world's sin, which is his chief characteristic. The sermon emphasizes that Jesus' purpose is to take away sin and reconcile people with God, and that he accomplished this through his death on the cross.
