This is a totally unfair charge and allegation. The word of God is indeed all we need. If we study His word, sit under godly Bible centred teaching, and seek the guidance of the Holy Spirit we have all we need.
There are no 'fix all' human books. You were blessed by the four books you listed. That's great! I am an avid reader of Christian books, but from your list I have olny read Platt. I thought it was challenging, but would not call it a book every Christian cannot live without.
I would say 'Pilgrim's Progress'. 'Foxes Book of Martyrs', Ironside's 'Holiness - the False and the True'. and 'Robinson Crusoe' are books that would bless, encourage, and challenge those who would read them. But I certainly would not say they are books that 'No Christian can live without' them. I would really miss 'The Valley of Vision,' a collection of puritan prayers, if I did not have a copy of it.
It is arrogant and presumptuous to say that anyone cannot live without my list of books apart from the Bible.
Well I was not being literal. Think of it more as a sellers phrase or lingo to get people into reading. Many publishers and stores try and get people into reading by using similar language.
