'Caution' in the Bible

Exercise appropriate caution so that there is no negligence in this matter. Why should danger increase to the point that kings sustain damage?"

So then, my dear ones, just as you have always obeyed [my instructions with enthusiasm], not only in my presence, but now much more in my absence, continue to work out your salvation [that is, cultivate it, bring it to full effect, actively pursue spiritual maturity] with awe-inspired fear and trembling [using serious caution and critical self-evaluation to avoid anything that might offend God or discredit the name of Christ].

And yet do not regard him as an enemy, but caution him as a brother.
