For even though I am absent [from you] in body, nevertheless I am with you in spirit, delighted to see your good discipline [as you stand shoulder to shoulder and form a solid front] and to see the stability of your faith in Christ [your steadfast reliance on Him and your unwavering confidence in His power, wisdom, and goodness].

Be wise in the way you live in front of outsiders [i.e., non-Christians], making the most of every opportunity.

Luke the physician, our dear friend, greets you, [as does] Demas.
