Robert Jenson once said, “It is a great achievement to know yourself a sinner.” It sounds paradoxical, but to know you’re a sinner puts you (and me) in a place to really listen to what Jesus is saying. Hence the parable of the publican and the pharisee. The dirty rotten scoundrel of a tax collector leaves worship justified, rather than the do-gooding religious adherent, because only he is able to confess that he is a sinner.
It’s not easy to receive this sermon from Jesus (particularly the woes) but somebody has to say such things. One must really know the people to which these words are delivered lest we leave thinking the preacher is talking about other people.
Bashing people with the law achieves nothing unless the one preaching is the One who comes to fulfill the Law.
Martin Luther reminds us that “God receives none but those who are forsaken, restores health to none but those who are sick, gives sight to none but the blind, and life to none but the dead. God does not give saintliness to any but sinners, nor wisdom to any but fools. In short: God has mercy on none but the wretched and gives grace to none but those who are in disgrace.”
