A Christian in a healthy church may eventually run across these two words. Some will dismiss them as just for theologians to understand. Cults avoid them because these tools expose their false doctrines. Those who really wish to explore the Bible will desire to become proficient in both. Hermeneutics involves methods of proper Bible study and exegesis is the result. Some may say that the Holy Spirit leads me into all truth (John16:13), and therefore I don't need anyone else. The truth is that he illuminates the Scriptures to the whole church and not just a corner. So, if our interpretation is very different, perhaps we may need to take a second look. We don't have to become proficient in Greek, Hebrew, Aramaic, Latin and German to become good Bible students. We have tools available to us from those who are experts: commentaries. The best commentaries go into great detail.
