Have you come across people who are so wicked that you avoid them because you think "Jesus would never associate with them"?
Listen to what the Lord Himself has to say, in Luke 5:27-32.
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."
