And what is preaching for? The answer comes without hesitation. It is for men's salvation. But the idea of what salvation is has never been entirely uniform or certain; and all through the history of preaching we can see that the character of preaching varied continually, rose or fell, enlarged or narrowed, with the constant variation of... ideas as to what it was to be saved. If salvation was here and now, salvation became a direct appeal to man's present life. If salvation was something future and far away, preaching died into remote whispers and only made itself graphic and forcible by the vivid pictures of torture addressed to the senses whose pain men most easily understood. If to be saved was to be saved from sin, preaching became spiritual. If to be saved was to be saved from punishment, preaching became forensic and economical. If salvation was the elevation of society, preaching became a lecture upon social science.... To the absence of any clear answer to that question, to the entire vagueness as to what [our] danger is, we owe the vagueness to which so many of our preachers preach.
