We need discernment. I think discernment is sorely lacking. Discernment is perception in the absence of judgment.
When it is said we are not to judge others, it does not mean not practicing discernment. Rather, it means being a judge over a person where we criticize and condemn him or her from a position of assumed moral superiority.
We seem to excel at this.
It has been said that what we despise most in others may be what we are most blind to in ourselves. Until we recognize this we will continue spiraling down in cycles of violence towards others and ourselves.
