Mark 2

Mark 2 is full of lessons.

A paralyzed man was brought to Jesus, and Jesus forgave him. Some scribes thought that He was blashpheming, so to teach them that He was not Jesus also healed the man. It doesn't sound like Jesus was condemning the scribes, but rather giving them a sign to correct their thinking. After that it says that all of them - including the scribes - were astounded and glorified God.

Then Jesus called one of His most surprising disciple draft picks - a tax collector. Not only did Jesus call Levi to follow Him, but Jesus went to Levi's house and hung out with Levi's friends. The Pharisees questioned why Jesus would hang out with people like that and He responded that He came to save exactly those type of people.

Then some people came and asked Jesus why His disciples didn't fast. Maybe they thought that Jesus was teaching an "easier" form of religion compared to the others. But Jesus corrected them and told them that His follower will also fast in due time - not as a religious obligation, but as a sign of their relationship with Him.

Jesus taught them that new ways of thinking do not fit into the status quo. He was teaching new things, and forming the new covenant, and people were going to have to give up some of thier old ways (religious traditions) in order to follow Him.

Then Jesus taught that God gave laws, but also has grace designed into those laws. The Pharisees were being very strict with Jesus and His disciples - basically accusing them of "harvesting crops" on the Sabbath, even though they were only getting a snack for themselves. There's a difference between putting in a full day's work in the field verses just getting a snack for yourself, and God has grace for such things.
