Commentaries:
Jamieson, Fausset, and Brown
Wherefore—seeing that ye need to walk so circumspectly, choosing and using the right opportunity of good.
unwise—a different Greek word from that in Ephesians 5:15. Translate, "foolish," or "senseless."
understanding—not merely knowing as a matter of fact (Luke 12:47), but knowing with understanding.
the will of the Lord—as to how each opportunity is to be used. The Lord's will, ultimately, is our "sanctification" (I Thessalonians 4:3); and that "in every thing," meantime, we should "give thanks" (I Thessalonians 5:18; compare above, Ephesians 5:10).
