Colossians 4:3-5

Amplified Bible

³ 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; ⁴ that I may make it clear [and speak boldly and unfold the mystery] in the way I should.

⁵ Conduct yourself with wisdom in your interactions with outsiders (non-believers), make the most of each opportunity [treating it as something precious].
