Chapters 1 through 4 showed Jesus more or less avoiding publicity. Here, in chapter 5, He will begin to openly challenge the local religious leaders. This chapter is Jesus' first major answer to His critics in this Gospel. The fact that Jesus is willing to heal on the Sabbath sets up a theme of His upcoming disagreements with the Pharisees. Jesus also provides important perspective on the relationship between evidence and faith, which He will expand on in later chapters. This chapter also establishes a key point made by Jesus' critics: His claims to be God.
