Lloyd-Jones has some excellent comments also (continuing from the last post) on the relationship of the doctrine of the wrath of God to the practical ins and outs of evangelism:
Why is it that people are not Christians and not members of the Christian Church? Why does the Lord Jesus Christ not come into their calculations at all? In the last analysis there is only one answer to that question: they do not believe in Him because they have never seen any need of Him.And they have never seen any need of Him because they have never realised that they are sinners. And they have never realised that they are sinners because they have never realised the truth about the holiness of God and the justice and the righteousness of God; they have never known anything about God as the Judge eternal and about the wrath of God against the sin of man. So you see this doctrine is essential in evangelism.
