W.M. Easton emphasizes the importance of holding fast to the unchanging truth of Scripture, particularly regarding the Person of Christ, and the need to resist the temptation to deviate from the foundational teachings of the apostles. He highlights the progression of divine revelation throughout history, from the early days of the Church to the full understanding of the Church as the Body of Christ and the House of God. Easton stresses the necessity of acting upon the complete revelation of God's Word, even in the midst of the Church's ruin, and the importance of maintaining Scriptural discipline and separation from unfaithfulness to Christ.
