Generation after generation has read the insights of its writers. This is why fresh statements of old truth are always needed. Without them people will read error.
Daniel Webster once said, "If religious books are not widely circulated among the masses in this country, I do not know what is going to become of us as a nation. If truth be not diffused, error will be; if God and His Word are not known and received, the devil and his works will gain the ascendancy; if the evangelical volume does not reach every hamlet, the pages of a corrupt and licentious literature will."1
Millions of people are going to read. If they don't read contemporary Christian books, they are going to read contemporary secular books. They will read.
It is amazing to watch people in the airports. At any given moment there must be hundreds of thousands of people reading just in airports. One of the things we Christians need to be committed to, besides reading, is giving away solid books to those who might read them, but would never buy them.
The ripple effect is incalculable. Consider this illustration: A book by Richard Sibbes, one of the choicest of the Puritan writers, was read by Richard Baxter, who was greatly blessed by it. Baxter then wrote his Call to the Unconverted which deeply influenced Philip Doddridge, who in turn wrote The Rise and Progress of Religion in the Soul. This brought the young William Wilberforce, subsequent English statesman and foe of slavery, to serious thoughts of eternity. Wilberforce wrote his Practical Book of Christianity which fired the soul of Leigh Richmond. Richmond, in turn, wrote The Dairyman's Daughter, a book that brought thousands to the Lord, helping Thomas Chalmers the great preacher, among others.2
It seems to me that in a literate culture like ours, where most of us know how to read and where books are available, the Biblical mandate is: keep on reading what will open the Holy Scriptures to you more and more. And keep praying for Bible-saturated writers. There are many great old books to read. But each new generation needs its own writers to make the message fresh. Read and pray. And then obey.
