Do we only heal the healthy?

Mark 2:13-17 (TNIV) -

13 Once again Jesus went out beside the lake. A large crowd came to him, and he began to teach them. 14 As he walked along, he saw Levi son of Alphaeus sitting at the tax collector's booth. "Follow me," Jesus told him, and Levi got up and followed him.

15 While Jesus was having dinner at Levi's house, many tax collectors and sinners were eating with him and his disciples, for there were many who followed him. 16 When the teachers of the law who were Pharisees saw him eating with the sinners and tax collectors, they asked his disciples: "Why does he eat with tax collectors and sinners?"

17 On hearing this, Jesus said to them, "It is not the healthy who need a doctor, but the sick. I have not come to call the righteous, but sinners."

My thoughts -

Do we only heal the healthy? Do we only preach to the converted? Do we build large churches that are self contained communities so that we don't have to deal with people who aren't like us? Have we isolated ourselves from non-believers? Have we created our own counterculture to be separate from what we call "the world"?

Jesus didn't build a mega-church and wait for people to come to him. He went and spent time with "sinners" where they were. (I hate that term, "sinners", by the way. We are all sinners. There's no sense in trying to label people we think are worse. We all have sinned and all need grace.) If we want to reach people we need to minister to the needs of our communities, not build our own communities to escape them. We don't just need to be shelter for the converted to take refuge in.
