Many practice the historical-grammatical method using the inductive method, a general three-fold approach to the text: observation, interpretation, and application. Each step builds upon the other, which follows in order. The first step of observation involves an examination of words, structure, structural relationships and literary forms. After observations are formed, then the second step of interpretation involves asking interpretative questions, formulating answers to those questions, integration and summarization of the passage. After the meaning is derived through interpretation, the third step of application involves determining both the theoretical and practical significance of the text and appropriately applying this significance to today's modern context. There is also a heavy emphasis on personal application that extends into all aspects of the practitioner's life. Theologian Robert Traina, in his 1952 "Methodical Bible Study", wrote that "the applicatory step is that for which all else exists. It represents the final purpose of Bible study."
