In chapters 1-4 we were introduced to the person of the King. In 5-7, the principles of the King. 8-9 display the power/authority of the King. This is important because as we wind up Chapter 9 and segue in to Chapter 10 we receive the commands of the King. His main command is simple: share the wonderful gift He freely gave to us. How can anyone possibly claim to believe they have found the only path to eternal life, yet selfishly keep that knowledge from the ones they profess to love?
