No one is more critical of the failures of God's people than Jesus. In his six "woes" to the Pharisees and teachers of the law, Jesus not only eviscerates the hypocrisies of false religion, but warns true believers against falling into the same errors. Ultimately, the integrity of the Gospel is not preserved by Christians behaving perfectly, but by acknowledging their chronic weakness, returning constantly to the well of God's grace in the Gospel, and seeking the power of the Holy Spirit to keep changing over time.
