Colossians 4:2-6 KJV

2 Continue in prayer, and watch in the same with thanksgiving;
3 Withal praying also for us, that God would open unto us a door of utterance, to speak the mystery of Christ, for which I am also in bonds :
4 That I may make it manifest , as I ought to speak .
5 Walk in wisdom toward them that are without, redeeming the time.
6 Let your speech be alway with grace, seasoned with salt, that ye may know how ye ought to answer every man.
