Colossians 4:2-6 (NRSV)
2 Devote yourselves to prayer, keeping alert in it with thanksgiving. 3 At the same time pray for us as well that God will open to us a door for the word, that we may declare the mystery of Christ, for which I am in prison, 4 so that I may reveal it clearly, as I should. 5 Conduct yourselves wisely toward outsiders, making the most of the time. 6 Let your speech always be gracious, seasoned with salt, so that you may know how you ought to answer everyone.
