The sermon examines Westminster Confession Chapter 1, Paragraph 10 to establish Scripture as the supreme judge in all religious controversies. It argues that spiritual truth requires divine illumination by the Holy Spirit, contrasting this with the Enlightenment's erroneous elevation of unaided human reason. The preacher defines biblical faith not as blind belief but as confident reliance on God's reliable promises and historical acts. Additionally, the text critiques modern relativism and theological liberalism for undermining the Bible's inerrancy and authority. Ultimately, the message emphasizes that proper interpretation depends on recognizing Christ revealed throughout all of Scripture.
