Advice on evangelism needs to be tailored to individual situations. For instance, I know someone who needs to be encouraged to speak less and work more. That would be a better testimony for him because he has certainly let his work colleagues know about Jesus. It's not that I don't want him to witness about Jesus, but I have a lot of sympathy for his employer. He is paying for work to be done.

You don't know if they have any non-Christian friends or if they have ever shared the gospel with anybody in the last 30 years. It's depressing going to prayer meetings like that. I don't want to pray like that.
