The document discusses the topic of heresies and how God allows them to come into the church. It says heresies are used by God to sift the chaff from the wheat by leading people to deeper Bible study. While heresies are dangerous, God can use them for good by prompting believers to thoroughly examine what they believe in light of Scripture alone. The document warns that superficial knowledge is not enough and emphasizes the need for believers to study the Bible, Spirit of Prophecy, and hold to fundamental principles based on authority.
