“At the time of the Reformation, to stop unbridled, speculative, and fanciful interpretations of Scripture, the Reformers set forth the fundamental axiom that should govern all biblical interpretation. It is called the analogy of faith, which basically means that Holy Scripture is its own interpreter. In other words, we are to interpret Scripture according to Scripture. That is, the supreme arbiter in interpreting the meaning of a particular verse in Scripture is the overall teaching of the Bible.” (R.C. Sproul)
