Here’s a short excerpt from one of John Piper’s sermons (Get Wisdom). It’s amazing what one can accomplish with just 15 minutes of Bible and/or Theology reading each day.
Since wisdom is found in the Word of God, we must apply ourselves in study and meditation to know the Word and do it. “The law of the Lord is perfect, reviving the soul; the testimony of the Lord is sure, making wise the simple.” (Psalm 19:7). Therefore, we must devote ourselves to know and understand the testimonies of the Lord. And here I commend not only faithful Bible study, but also regular reading of great books on theology and biblical interpretation, books that distill the wisdom of the greatest students of the word over the past 1900 years.
Now, I know what you are thinking: I don’t have the time or the ability to get anywhere in books like that. So I want to show you something really encouraging. When this was shown to me about four years ago by my pastor, it changed my life. Most of us don’t aspire very high in our reading because we don’t feel like there is any hope.
But listen to this: Suppose you read about 250 words a minute and that you resolve to devote just 15 minutes a day to serious theological reading to deepen your grasp of biblical truth. In one year (365 days) you would read for 5,475 minutes. Multiply that times 250 words per minute and you get 1,368,750 words per year. Now most books have between 300 and 400 words per page. So if we take 350 words per page and divide that into 1,368,750 words per year, we get 3,910 pages per year. This means that at 250 words a minute, 15 minutes a day, you could read about 20 average sized books a year!
Now, the goal is not numbers. It would be incorrect to think that the book count is the sole purpose. But our minds do need something to ruminate on. Farmers know what the word “ruminate” means. It means to chew over and over, the way a cow chews on cud. We need to fill our minds with good biblical and theological truth so that it can chew on something throughout the day.
Be like a cow and chew on that.
