Colossians 4:5-9

5Conduct yourself with wisdom in your interactions with outsiders (non-believers), make the most of each opportunity [treating it as something precious].

6Let your speech at all times be gracious and pleasant, seasoned with salt, so that you will know how to answer each one [who questions you].

7As to all my affairs, Tychicus, who is a much-loved brother and faithful assistant and fellow bond-servant in the Lord, will give you all the information.

8I have sent him to you for this very purpose, that you may know how we are doing and that he may encourage your hearts;

9and with him is Onesimus, our faithful and beloved brother, who is one of you. They will let you know everything about the situation here [in Rome].
