Colossians 4:2-6 NKJV

2 Continue earnestly in prayer, being vigilant in it with thanksgiving;
3 meanwhile praying also for us, that God would open to us a door for the word, to speak the mystery of Christ, for which I am also in chains,
4 that I may make it manifest, as I ought to speak.
5 Walk in wisdom toward those who are outside, redeeming the time.
6 Let your speech always be with grace, seasoned with salt, that you may know how you ought to answer each one.
