Colossians 4:2-6

Be persistent and devoted to prayer, being alert and focused in your prayer life with an attitude of thanksgiving. At the same time pray for us, too, that God will open a door [of opportunity] to us for the word, to proclaim the mystery of Christ, for which I have been imprisoned; that I may make it clear [and speak boldly and unfold the mystery] in the way I should. Conduct yourself with wisdom in your interactions with outsiders (non-believers), make the most of each opportunity [treating it as something precious]. Let your speech at all times be gracious and pleasant, seasoned with salt, so that you will know how to answer each one [who questions you].
