Colossians 4:2-6

Devote yourselves  to prayer; stay alert in it with thanksgiving. At the same time, pray also for us that God may open a door  to us for the word, to speak the mystery of Christ,  for which I am in chains,  so that I may make it known as I should. Act wisely toward outsiders, making the most of the time.  Let your speech always be gracious, seasoned with salt,  so that you may know how you should answer each person.
