Read Luke 5 today.

One of the stories within this chapter is the calling of Levi to be a disciple of Jesus. Levi was an unlikely choice. He was a tax collector, someone who was looked down on by the other people of the community. Why would Jesus invite someone without the credentials of ‘righteousness’ to be a disciple?
Jesus explained that He came to call those who are willing to make an honest assessment of themselves. Those who perceive themselves to be righteous, to already be ‘good enough,’ cannot imagine any need for Jesus. It is not that Jesus would not have them, but that they would not have Him.
What is your assessment of yourself? Do you consider yourself to be ‘basically a good person’ and therefore good enough? Do you look put all of your thoughts and actions on the scales and hope the good balances out the bad? Or do you recognize the gaps between yourself and God’s righteousness, and acknowledge your need for Jesus?
Luke 5:27-32 NLT
Later, as Jesus left the town, he saw a tax collector named Levi sitting at his tax collector’s booth. “Follow me and be my disciple,” Jesus said to him. [28] So Levi got up, left everything, and followed him. [29] Later, Levi held a banquet in his home with Jesus as the guest of honor. Many of Levi’s fellow tax collectors and other guests also ate with them. [30] But the Pharisees and their teachers of religious law complained bitterly to Jesus’ disciples, “Why do you eat and drink with such scum?” [31] Jesus answered them, “Healthy people don’t need a doctor-sick people do. [32] I have come to call not those who think they are righteous, but those who know they are sinners and need to repent.”
