This is the Log in our eye.
We are told to Judge the spiritual condition of other by Christ.. But He cautions that we judge correctly..because the measure we use to measure other is the measure used to measure us..
Jhn 7:24 Judge not according to the appearance, but judge righteous judgment.
We are told not to be yoked with the unsaved.. that requires a judgment ...
1Cr 6:2 Do ye not know that the saints shall judge the world? and if the world shall be judged by you, are ye unworthy to judge the smallest matters?
The only verse the unsaved seem to know is "judge not " but they do not seem to understand the point..
