There is no true evangelism without the doctrine of sin, but I say that a gospel which merely says ‘Come to Jesus,’ and offers Him as a Friend, and offers a marvelous, new life, without convicting of sin, is not New Testament evangelism. The essence of evangelism is to start by preaching the law; and it is because the law has not been preached that we have had so much superficial evangelism. Go through the ministry of our Lord Himself and you cannot but get the impression that at times, far from pressing people to follow Him and to decide for Him, He put great obstacles in their way. He said in effect: ‘Do you realize what you are doing? Have you counted the cost? Do you realize where it may lead you? Do you know that it means denying yourself, taking up your cross daily and following Me?’ True evangelism, I say, because of this doctrine of sin, must always start by preaching the law. This means that we must explain that mankind is confronted by the holiness of God, by His demands, and also by the consequences of sin. It is the Son of God Himself who speaks about being cast into hell. If you do not like the doctrine of hell you are just disagreeing with Jesus Christ. He, the Son of God, believed in hell; and it is in His exposure of the true nature of sin that He teaches that sin ultimately lands men in hell. So evangelism must start with the holiness of God, the sinfulness of man, the demands of the law, the punishment meted out by the law and the eternal consequences of evil and wrongdoing. It is only the man who is brought to see his guilt in this way who flies to Christ for deliverance and redemption. Any belief in the Lord Jesus Christ which is not based on that is not a true belief in Him. You can have a psychological belief even in the Lord Jesus Christ; but a true belief sees in Him one who delivers us from the curse of the law. True evangelism starts like that, and obviously is primarily a call to repentance, ‘repentance toward God, and faith toward our Lord Jesus Christ.’
