Colossians 4:5-6

Amplified Bible, Classic Edition

⁵ Behave yourselves wisely [living prudently and with discretion] in your relations with those of the outside world (the non-Christians), making the very most of the time and seizing (buying up) the opportunity.

⁶ Let your speech at all times be gracious (pleasant and winsome), seasoned [as it were] with salt, [so that you may never be at a loss] to know how you ought to answer anyone [who puts a question to you].
