"I did not come to call the righteous, but sinners"

What would this look like today?

   Matthew decided to have a banquet to introduce Jesus to his friends. Like most new believers, he wanted to bring everyone he knew to Christ. Luke 5:29 reveals that Matthew (who was also known as Levi) held the banquet in his own house. Jesus was the honored guest. This gathering was attended by some of the most notorious, base, villainous people in the history of banquets. The only people Matthew knew were sordid types, wretched sinners, because no one else would associate with him. The respectable people despised him. His friends were thieves, blasphemers, prostitutes, con artists, swindlers, and other tax collectors - the riffraff of society.
  Supercilious religious types would say, of course, that Jesus shouldn't go to a banquet with such degenerates. That is exactly what the Pharisees thought. But that was not the way of the Savior. Matthew 11:19 indicates that He was known among the people as "a friend of tax-gatherers and sinners." This very banquet probably gave rise to that perception. The Pharisees meant it derisively, but it was nonetheless a fitting title for the Son of Man.
  Matthew 9:10 sets the scene: "It happened that as He was reclining at the table in the house, behold, many tax-gatherers and sinners came and were dining with Jesus and His disciples." This was so scandalous to the self-righteous Pharisees that they could hardly conceal their shock. If he were really the Messiah, they thought, he would be having a dinner for us!

The Gospel According to Jesus by John MacArthur

"It is not those who are healthy who need a physician, but those who are sick. But go and learn what this means: 'I desire compassion, and not sacrifice,' for I did not come to call the righteous, but sinners."

Matthew 9:12-13
