While there are collective sins, however, everything begins in the heart of each individual man / woman. The first step is to recognize my own human frailty, my own sin: "Against you I sinned, I committed the evil you hate," David says to God after acknowledging his human weakness, which he manifests in Psalm 50 that he composed. Before wanting to judge others - and wanting to remove the straw they carry in their eyes - it is necessary for me to judge myself - and to take out the beam that I carry inside many times. Sometimes we tend to be very hard with others in our judgments, looks and comments, and very tolerant and lax with ourselves.
