I don't see a clerical class in the New Testament to which evangelism has been delegated. Preaching is not the only way to evangelize; it can happen in everyday conversations too. And you don't need a special gift to witness to the Lord in these situations.
Mark DeverAdvice 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.
Mark DeverAccording to the New Testament, the church is primarily a body of people who profess and give evidence that they have been saved by God's grace alone, for His glory alone, through faith alone, in Christ alone.
Mark DeverEvery believer should evangelize. I know some Christians think that evangelism is only for people with special gifts for it, but I don't believe the New Testament teaches that. While Paul does say that some believers have the call to be evangelists, all of us have the responsibility of evangelism.
Mark DeverI don't have any way to control the Spirit or create revival. I pray that the Holy Spirit would move upon the church, but at the same time, I want to busy evangelizing. I am not one of those people who moan and pray for revival all the time, but do nothing.
Mark DeverWe live in a time when people are increasingly skittish about evangelism - Christians and non-Christians alike. People are suspicious of evangelism, and misunderstand it, which contributes to our reluctance to share the gospel. When you add our fear of others' reactions as well as our natural laziness to the equation, it's not hard to see why we make such little progress in sharing our faith.
