Jesus asked, "Why do you notice the splinter in your brother's eye, but do not perceive the wooden beam in your own eye?" (Matthew 7.3). It's so easy to get upset over things or people because they turn out to be imperfect, and at the same time overlook our own imperfections (getting upset being one). If we are not perfect, how can we expect others to be perfect? It all comes down to "no sinner has the right to judge fellow sinners."
