The problem with the "Judge not" statement is that it is constantly mistranslated. It is referring to condemnation, not judgement. See the original Greek in Strong's.

In fact, this thread begins with this explanation. (See the top post in this thread.)

There is evil abounding on this planet, and evil wants nothing more than for people to be "tolerant" of it. Evil wants us to "judge not" the evil, so it can continue unhindered.

The Bible (which is where you get that quote from) constantly tells us to discern all things. We should become sharp enough to know the different between good and evil.

Many today would condemn the Masons for their participation in occult rituals and the destruction of modern civilization ("order from chaos"), but few realize that not only was Joseph Smith a Mason, the temple ceremonies that every Mormon goes through are very similar to Masonic utterances. In fact, some parts of the ceremony are taken word-for-word from Scottish Rite Masonry rituals, of which Joseph Smith was a member.

It's important to know the difference between good and evil because evil's intention is to kill, steal, and destroy. The way we avoid evil is by recognizing it, discerning it, judging it.

Don't let evil have it's way by tolerating the form of blindness that mantras "Judge not". This mantra does nothing more than attempt to blind those who have refused to awaken to the wisdom found in the most important Book ever written.

How "Judge Not" is Destroying America

When you tolerate evil, you're conspiring together with the enemy of your own soul.
