" A similar attitude causes some people to spurn the use of commentaries and similar resources in their Bible study, as if their own uninformed first impression is just as good as careful study using reference tools. It is becoming more and more common all the time to hear people say, 'I don't read commentaries and books about the Bible. I limit my study to the Bible itself.' That may sound very pious, but is it? Isn't it actually presumptuous? Are the written legacies of godly men of no value to us? Can someone who ignores study aids understand the Bible just as well as someone who is familiar with the scholarship of other godly teachers and pastors? "
