In an age of specialization, where our knowledge increases every day, we may adopt the idea that most Christians are 'specialized out' of evangelism. Most have not taken an apologetics course or a public speaking course; so evangelism is for the expert. But in 2 Corinthians 4, the apostle Paul reveals his evangelism technique. And we find out that any Christian is qualified to proclaim the Gospel to the lost. We are called to openly display the truth of God's Word to those who need to embrace it.
