Constructive Criticism

What is ever constructive about criticism?

Does it ever "build" anything? I mean other than the purveyor's idea of him or herself. Criticism means there is an assumed ideal. And the ideal is in the eye of the beholder. So it is, in fact,the author of the statement.

So where did the ideal originate. Who was the first authority and where did the concept come from? I love to watch dog shows and it is interesting to see exactly what is considered a "true" breed. There are a few really weird and kooky looking dogs. Who originally said that is a whatcha-ma-call-it and this is the most perfect one there is. Where did their authority come from?

As "Christians" we feel we have the ideal in front (or back) of us. In the embodiment of God incarnate, Jesus Christ. But when we judge, we are not using Him as the plumb line, but ourselves. If He came as the form of unconditional grace, any conditions we place on others are truly ours, not His. And if there is any standard we hold, it is ours. That is where the rub is. If it is do-able (we have proven that) then anything less you do is not up to par, which means you did not give it your all, therefore you are unworthy. But unworthy of what? Love that has no conditions?

You can't see it but I am scratching my head.
