"Master those books you have.  Read them thoroughly.  Bathe in them until they saturate you.  Read and reread them, masticate and digest them.  Let them go into your very self.  Pursue a good book several times and make notes and analyses of it.  A student will find that his mental constitution is more affected by one book thoroughly mastered than by twenty books he has merely skimmed.  Little learning and much pride come of hasty reading.  Some men are disabled from thinking by their putting meditation away for the sake of much reading.  In reading let your motto be, 'much, not many.'"

- Charles Spurgeon

“When you come, bring the cloak I left in Troas with Carpus, as well as the scrolls [books], especially the parchments." 2 Timothy 4:13

Paul had a few books left, perhaps wrapped up in the cloak, and Timothy was to be careful to bring them. Even an apostle must read. He is inspired, and yet he needs books. He had seen the Lord, and yet he needs books. The apostle says to Timothy, and so he says to every Christian reader, “Give yourself to reading." The person who never reads will never be read; the one who never quotes will never be quoted; those who will not use thoughts from the brains of others will prove that they have no brains of their own. What is true of ministry leaders is true for all Christians. We need to read. We must study as much as possible sound theological works and expositions of the Bible. We are persuaded that the best way to spend leisure time is to be either reading or praying. We may get much instruction from books that afterward we may use as a true weapon in our Lord and Master's service.
