The gospel is again explained. It is clear then that we must become practised in clear reasoned arguments in defence of the gospel. This is not really very hard because the number of issues raised by people are limited and so it is quite possible to learn and practice planned arguments or answers. Of course, it is not wise to know off an answer by rote. Rote answers, as with rote gospel presentations, leave an intelligent hearer cold.
Most people are particularly suspicious of the rote sales pitch.
The crucial thing is to know how the argument runs. It should be truthful. Winning an argument or answering a question through deceit has little merit. It certainly doesn't win God's favour nor does it do the hearer much good. They sooner or later sees through it.
