Christianity is not just involved with "salvation", but with the total man in the total world. The Christian message begins with the existence of God forever, and then with creation. It does not begin with salvation. We must be thankful for salvation, but the Christian message is more than that. Man has a value because he is made in the image of God.
Our life is half natural and half technological. Half-and-half is good. You cannot deny that high-tech is progress. We need it for jobs. Yet if you make only high-tech, you make war. So we must have a strong human element to keep modesty and natural life.
