It’s important to view things critically, to spot error, notice inaccuracies, and find ways to bring change. It should be done, as Roy says, with a critical eye but without a critical spirit. The purpose of criticism is to make corrections and to seek improvement by encouragement and a gentle spirit. Otherwise, we will become cynical and foster poor attitudes and behavior.
The soothing tongue is a tree of life, but a perverse tongue crushes the spirit. (Proverbs 15:4)
