What is the context?
Jesus teaches beside the sea, then calls Levi son of Alphaeus from his tax booth. Levi gets up and follows Him. In the parallel account, Matthew 9:9–13, the tax collector is called Matthew; Christians have traditionally understood these as two names for the same man. Mark does not describe a change of name.
The next scene brings Jesus and His disciples to a meal with many tax collectors and sinners. Luke 5:27–32 explains that Levi hosts the banquet at his own house. Some scribes who are Pharisees question why Jesus eats with these people. Their objection brings the purpose of His ministry into focus: whom has He come to call?
Jesus answers with the picture of a doctor going to sick people. Their need is the reason for His presence. Eating with sinners does not mean declaring their conduct harmless: Luke's account explicitly says He calls them to repentance. Levi's response gives the scene a concrete example of that change—he gets up to follow Jesus.
How is this passage commonly understood?
Christian readings commonly understand Jesus' meal as mercy toward sinners and a call to change, rather than approval of sin. Calvin on Matthew 9:12–13 and the US Catholic bishops' note on Mark 2:17 understand the healthy people in His comparison as those who consider themselves righteous, rather than a separate group with no need of God's help.
Where does this fit in God's plan?
In Matthew 9:13, Jesus explains this same meal by pointing to Hosea 6:6, where God puts mercy and knowing Him ahead of empty religious observance. Jesus' welcome does not abandon God's earlier purpose; it shows that purpose at work among people others want to keep at a distance.
The need reaches beyond the people around this table. Romans 3:9–26 includes both Jews and Gentiles under sin, then describes the grace and redemption God gives through Jesus Christ. The doctor picture helps us see why Jesus' saving work is needed by everyone, including people with a respectable religious life.
