He went out again beside the sea, and all the crowd was coming to him, and he was teaching them. And as he passed by, he saw Levi the son of Alphaeus sitting at the tax booth, and he said to him, “Follow me.” And he rose and followed him.
(Mark 2: 13-14 ESV)
Not only that Jesus can forgive sins, in fact he’s calling sinner to be His disciple! Tax collector at that time is one of the worst profession according to the law teachers, they’re seen as traitors to the Jews as they collect money for Roman authority. But Jesus doesn’t see that, he calls people to repent and follow Him :)
Levi in the end is the one who writes the account of Jesus, the book of Matthew :)
