Cannot believe that which is unknowable

If the Holy Scriptures were really so obscure a book that the meaning of all those passages which form the basis of articles of the Christian Creed could not be definitely ascertained, and if, as a result of this, we should have to acknowledge that without some other authority it would be impossible to decide which of two or several interpretations of Scripture-passages is the only correct one, - if these conditions, I say, we're true, the Scriptures could not be the Word of God. How could a book that leaves us groping in darkness and uncertainty regarding its essential contents serve as a revelation? - C.F.W. Walther, The Proper Distinction between Law and Gospel, pg. 59

"The Kingdom of God is not a Kingdom of ignorance, but of faith and, consequently, of knowledge; for it is beyond the ability of anyone to believe that which he is ignorant of." - Theodore Beza, Preface of Theodore Beza in The Christian Faith, pg. iv
