Should there be comma before and after "therefore" if occuring in a middle of sentence?

[n o s p a m p l e a s e]

It is, therefore, important.
It is therefore, important.
It is therefore important.

Which one of the above is correct from punctuation point of view?

Only the last one looks right to me. The word "therefore" is an integral
part of the sentence

Thanx. If it is in the beginning, should be a comma e.g. "Therefore,
tt is important"?

No, it's still an integral part of teh sentence.

There are only commas around so-called "sentence adverbs", i.e. adverbs
referring to the whole sentence - examples are "however", "nevertheless"
- and commas after ordinal adverbs such as "firstly", "lastly" at the
beginning of a sentence - although these commas are often omitted.

I disagree -
I think it should be: Therefore,is it important.....
therefore refers to a previous sentence asserting some fact.the speaker goes
on to ask a question.and a natural pause is necessary.
