Suppose there are two people who finish cleaning out a chimney. The one whose face got less dirty washes his face, but the other whose face got more stained with ashes and dirt doesnt wash his face. This is the result of being able to see each other, but not being able to see oneself. People are usually good at finding others specks or faults though they are poor at finding their own. They just blame others or the environment for their problems. Such people cannot discover themselves. This is why I hope you will continually discover your shortcomings based on the Word of God recorded in Luke 6:41-42 and attain a pure heart.
