The author begins by identifying the prevailing problem in the church today, that doctrine seems to be neglected. The "heart vs. head heresy" is cited as the problem. Consequently the author then traces where false doctrine harmed or was a potential harm to the church, and then considers the positive effects of sound doctrine. The author concludes by explaining the link and relationship between theory and practice, or doctrine and life.
This chapter wants to make clear how sound doctrine helps us to read and teach the Bible wisely. Sound doctrine keeps us from inferring things from Scripture that are untrue. The Bible should be read as a single story; understanding the unity of that story is not always so simple. The chapter thus presents general rules for the reading and interpretation of Scripture.
Should we only use biblical terms in order to stop heresy and promote sound doctrine? This article maintains that since words are a means of communicating ideas, and ministers are called to explain and preach the word of God, ministers should be free to use terminology that will help in understanding biblical doctrine.
