examination

In the same way every good tree produces good fruit, but a rotten tree produces bad fruit.  A good tree cannot produce bad fruit, and a rotten tree cannot produce good fruit.  Any tree that fails to produce good fruit is cut down and thrown into a fire.  Matthew 17:17-19 (NOG)

Yes, the way to identify a tree or a person is by the kind of fruit that is produced.

Measure the motives of your heart. Examine yourself in the light of my love.  At Passover the lamb was examined, to be found perfect. Even I was publically and brutally examined. No imperfection was found.

Stand in the light of my love. In me there is life; In me there is no imperfection.  Partake freely of my fruit.
