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. So Levi got up, left everything, and followed him.
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. But the Pharisees and their teachers of religious law complained bitterly to Jesus' disciples, "Why do you eat and drink with such scum?" Jesus answered them, "Healthy people don't need a doctor—sick people do. I have come to call not those who think they are righteous, but those who know they are sinners and need to repent."
~Luke 5:27-32
It is shameful that Christians (including me) try to present themselves as better than the "sinners" of the world. Every time that we do it, we are caught in our own hypocracy. We are no better than anyone else; we are no more "good". As Jesus himself said, no one is good except God alone. This is proven over and over. Christians are not better than any other sinner in the world.
What sets us apart is that we are sinners who have found grace. As dirty and shameful as we are at times, God loves us and looks on us with grace when we come to him in faith. It is a gift that we do not deserve... ever...
"Christianity is like one beggar telling another beggar where to find Bread" ~Vance Havner (famous southern pastor)
