In the New Testament, all Christians were to share in the task of evangelism. The first way they were to do this was by sharing the caring, agape love that Jesus taught with all around them—love that was forgiving, caring, unselfish, generous, and active—love that was to be shared with friends and enemies alike. The second way they were to do this was by being ready to give an answer to anyone who asked about their hope, and people would ask when they witnessed the Christian love practiced by these people.
But to communicate an evangelistic message in this culture, the primary emphasis needs to return to what was the primary emphasis in the New Testament: Jesus is Lord. Once we get a person to accept that, everything else falls into place. It’s not complex, it’s on the vast majority of pages in the New Testament, often multiple times, and it’s the real key. When people want to know what that means, the answer is again simple—a life of Christian love lived for God. When it’s time for Christian immersion, again the answer is simple if Jesus is Lord. Anybody can do that.
One more item. If we have people who bring someone to the Lord actually participate in the immersion, they become motivated to do that again, and others become motivated to do the same. Wouldn’t that be awesome? The too common practice of having the local professional “priest” do the immersion is definitely not biblical. Read 1 Corinthians and see how Paul turned that practice over to his converts almost immediately.
