Choose as to what? Judge as to what? To separate as to what? To approve as to what?
You may note that I was just replying to your comment on the Greek word used in John 3:18. Some translations say "condemned" some say "judged" and I think they are saying the same thing in the context. SO to answer your question above:
Choose as to what? - to be condemned or not to be condemned
Judge as to what? - to be judged guilty or not guilty
To separate as to what? - to be separated from the guilty
To approve as to what? - to be approved as not condemned, not guilty, to be approved righteous.
