The sufficiency of Scripture

In my study of Daniel, I came across this quote of Dr. Wayne Grudem on the sufficiency of Scripture: "The sufficiency of Scripture means that Scripture contained all the words of God he intended his people to have at each stage of redemptive history, and that it now contains all the words of God we need for salvation, for trusting him perfectly, and for obeying him perfectly."
