A godly man will seek the kind of wisdom that comes from a multitude of counselors. This means he should read from more than one fountain, and on more than one subject.
When can you get this type of reading done? Maybe you can take ten minutes during lunch or use your fifteen minute afternoon break for a few more pages. If you read only 10-pages per day that becomes 3,650 pages in a year. If the average non-fiction book is around 220 pages, after one year you will have read over 16 books.
A Seminary student in a known Seminary gets assigned up to 125 books over their 3 to 3-1/2 years in training. This averages to around 36 books a year. And these are full-time students who are taught and guided in between.
However, many of them do not have the benefit of learning along the way. Rather, the focus is on condensed knowledge over a short period of time, which is not the approach I’m suggesting by which God fashions elders over decades.
Also, certain days of the week permit for more time to read. Saturdays, alongside of chores and work and errand-running and quality time with wife and kids, may still allow for a good hour or two of study. Sunday, affords everyone a day for rest and worship. God has set aside this day for good purposes and responsible men will take advantage of it. Putting it strictly to the numbers, if we counted extra book reading (not your 40-minutes of devotional reading) just the additional 10-pages on Monday thru Friday plus 20-pages every Saturday and 40-pages on Sundays, your total page amount would become 5,730 pages in a year (give or take based on the calendar year). This now equates to 26 books a year.
