How do we know the doctrine of judging others is true?

Matthew 7:1-5 warns against a critical, judgmental attitude that overlooks our own faults while scrutinizing others. Jesus teaches that we should first remove the 'beam' from our own eye before attempting to help others with their 'mote'. This does not mean we should never judge, but rather that our judgments must be grounded in self-reflection and humility. Judging rightly entails examining our own hearts and lives first, as true discernment comes from a place of grace and self-awareness, aligning with the broader biblical principle of love and restoration.
