Discern Both Good and Evil

That would require a judgment wouldn't it? 

Hebrews 5:12-14(NKJV)

12For though by this time you ought to be teachers, you need someone to teach you again the first principles of the oracles of God; and you have come to need milk and not solid food. 

13For everyone who partakes only of milk is unskilled in the word of righteousness, for he is a babe. 

14But solid food belongs to those who are of full age, that is, those who by reason of use have their senses exercised to discern both good and evil.

Yes this is yet again another musing about the whole "thou shall not judge" thing.  All together now:

"The Bible is a book of balance."  so saith the Common Christian :)

But seriously.  Here again we have a Scripture that plainly tells us that as mature Christians we are to use our senses to discern both good and evil.  What does that mean?

It means we are to evaluate things based on our knowledge of Scripture coupled with the leading of the Holy Spirit who was given to us in part to help us discern the Truth.  We are to use our intellect and our senses to come to a conclusion as to whether something is good or evil.  That requires that we make a judgment. 

So what is the difference?  Here is what I believe the difference is.  In the "thou shall not judge" passage I believe it is referring to judging what someone's relationship with God is.  Shouldn't do that.  Only God and that person truly know what that relationship is. 

The difference I see in the Scriptures that tell us to make judgments is that it is telling us to examine concrete things like behavior and compare that behavior to what God through Scripture has defined as good or evil. 

Does that make sense?
