An evangelist is someone who has a passion to lead people to the Lord. But every believer should have a passion for souls. When presenting the Gospel, we are not just presenting a theory about God but the factual account of God's dealings with man as revealed through His Word, with the ultimate witness being the bodily resurrection of Jesus. Our personal witness of the reality of Jesus being alive in our lives brings Christ from theory to reality.

The early Christians had experienced the love of Christ in an intimate and life-transforming way. This motivated them to reach their known world with the Gospel of Christ more than any generation of Christians has done since. They didn't have the benefits of our modern technology, but they did have the benefit of being full of the love of Christ. Experiencing the love of Christ causes us to be filled with the fullness of God (Ephesians 3:19) and makes us a witness that the world cannot resist (John 13:35).

Today, much of the emphasis of the church is placed on techniques of evangelism or spiritual warfare. We motivate people to witness through feelings of guilt or punishment if they don't. Much of our evangelism has become as dead and non-productive as that of the cults who knock on doors and argue people into their way of thinking. 

The early Christians had a much greater impact on their world because they were full of, and motivated by, the love of God. The church needs a revival of our personal relationship with the Lord. When we can say with Paul that the love of Christ constrains us, then we will impact our world for the Lord too. You can't give away what you don't possess. We need to personally know the love of Christ in an experiential way before we try to share it with others.
