For the Son of Man came to seek and save what was lost.
No one can change another person. You can only change yourself. You will never reach someone if you are never near someone. I can see why people would be inclined to stay away from sinners, but the beauty and majesty of Holiness is that it has the power to purify anything it touches. Messiah was in contact with sinners because he loved them and only by being with them and showing his love, could he effectively awaken them to repentance and more abundant life. That is a hard example to follow. May we have the strength of heart to love people where they are for no other reason then we are all children of one Father.
