John 3:19 - 36

Jesus concludes His conversation with Nicodemus by stating that light drives out darkness.  However, in the world, men prefer the darkness as it is more in line with their evil desires.  The one who comes to Jesus will find that the light of His presence illuminates the wickedness of their evil deeds and highlights the glory of God seen in their good deeds.

The followers of John, the baptizer, ask their teacher about Jesus.  Specifically, they ask about whether or not He is a threat to their work.  John's response is that they should rejoice that Jesus has come.  He will increase in His ministry, while John's would decline.  This is not simply a matter of a fickle audience; it is a sign that God truly has come and that John and Jesus are fulfilling their parts in a divine plan for the salvation of mankind.
