Praying for opportunities to speak about Jesus is an important step in being an effective gospel witness (Col 4:2-4). And living in a way that anticipates such opportunities is another important step (Col 4:5). But when you take these steps, you need to be prepared to speak when opportunities come your way (Col 4:6). Perhaps it is appropriate to call this responsive evangelism, that is, learning how to respond when unplanned witnessing opportunities occur. To this end, Paul gives valuable advice.
