Packer’s favorite book of the Bible is Ecclesiastes (as it is for me). What the Preacher “says about life’s best being an enjoyment of the basics – one’s work, meals, marriage” makes Packer “want to laugh and cheer” because this is what he has felt all his adult life. The text “that runs most constantly around [his] heart is Ecclesiastes’s exit line – ‘Fear God and keep His commandments, for this is the whole duty of man,’ meaning everybody.”
When Packer was a student, he was convicted by the suggestion from a speaker that a good way to grasp the full meaning of a part of Scripture is to read it ten times. One Sunday, Packer read the Book of Hebrews ten times, and it “remains one of the richest books of Scripture” to him.
The son of a railroad employee, Packer has an extensive collection of books about trains.
