Luke 5:29-31
29 Then Levi held a great banquet for Jesus at his house, and a large crowd of tax collectors and others were eating with them. 30 But the Pharisees and the teachers of the law who belonged to their sect complained to his disciples, “Why do you eat and drink with tax collectors and ‘sinners’?”
31 Jesus answered them, “It is not the healthy who need a doctor, but the sick. 32 I have not come to call the righteous, but sinners to repentance.”

Many well meaning Christians have read over the above passage but never have put it into practice. In fact it’s not all that unusual for Christians to in effect shoot their wounded.
Take for example the fallen away Christian – the wounded Christian. The kneejerk reaction at the very least is to turn their back on sinners. The other common practice is to confront the sinner negatively thereby insuring an equally negative reaction by the sinner toward Christianity.
There’s the old adage that says “Hate the sin; love the sinner.” If only we could separate the sin from the sinner in our own minds.
