according to my firm expectation and hope, that I shall be confounded by no event, but that with all boldness, as always hitherto, Christ shall now also be magnified in my body, whether by my life or death.

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].
