William Burkitt on Ephesians 5:17

As if he had said, "Seeing the times are so perilous, and your opportunities of doing good so uncertain, be wise, and understand what are the proper duties of your place and station, and know how to manage yourselves in every relation, with reference to the duties, dangers, snares, and temptations, which may be before you, and this according to the will of God revealed in his word.

Learn hence, That it is a special part of divine wisdom to understand and know what is the mind and will of God concerning us, in every condition of life which his providence brings us into; to the intent that we may fill up every relation with the proper duties of it, to the glory of God and our own and other's satisfaction: Be not unwise, but understand what the will of the Lord is.
