This comes from the Parable of the Pharisee and the Tax Collector that Jesus taught to a group of self-righteous, haughty people. It says in verse 10 that both men went up to the Temple to pray. The Pharisee pushed his way up to the front of the crowd in order to be seen and heard by everyone, and once there, proceeded to pray loudly and arrogantly…basically telling God how lucky He was to have him. On the other hand, the Tax Collector stood way back in the courtyard, daring not to even look up to heaven, but rather beating his breast and whispering, “God have mercy on me.” In Jeremiah 31:19 it says, “After I strayed, I repented; after I came to understanding, I beat my breast. I was ashamed and humiliated because I bore the disgrace of my youth.” The road from self-deception to self-awareness requires acknowledgement…admitting I’m just as sinful as those around me and not one bit more righteous.
