To deny the perspicuity of Scripture is to find fault with God, for if the Scripture cannot be understood, then the Holy Spirit failed in his purpose for writing it. William Whitaker wrote:

If the Scriptures be so obscure and difficult to be understood, that they cannot be read with advantage by the people, then this hath happened, either because the Holy Spirit could not write more plainly, or because he would not. No one will say that he could not: and that he would not, is repugnant to the end of the writing; because God willed that they should be written and committed to letters for the very end, that we should learn what was written, and thence derive a knowledge of his will; as is plain from Rom. xv. 4, “Whatsoever things were written, were written for our learning:” where Paul speaks not only of the learned, but of the whole multitude of the faithful. The Scriptures, therefore, are clear. Besides, God does not mock us when he bids us to read the scriptures; but he would have us read the scriptures so that we may know and understand them. Again, the scripture is called a rule, a standard, a mark, laid open to the eyes of all: it is, therefore, of necessity easy and clear. Thus then we briefly conclude this argument. The Holy Spirit willed the scriptures to be consigned to writing in order that we might understand them; and that this was the end which he proposed there are many things in the scriptures themselves that testify: therefore, they are so written as to be intelligible by us, of else the Holy Spirit hath not gained his end; which cannot be thought without impiety.
