Colossians 4:2-6
2 Devote yourselves to prayer, being watchful and thankful. 3 And pray for us, too, that God may open a door for our message, so that we may proclaim the mystery of Christ, for which I am in chains. 4 Pray that I may proclaim it clearly, as I should. 5 Be wise in the way you act toward outsiders; make the most of every opportunity. 6 Let your conversation be always full of grace, seasoned with salt, so that you may know how to answer everyone.
Ephesians 6:19-20
19 Pray also for me, that whenever I speak, words may be given me so that I will fearlessly make known the mystery of the gospel, 20 for which I am an ambassador in chains. Pray that I may declare it fearlessly, as I should.
