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