Bible courses in this series do not normally quote sources outside the Bible. This course has a few exceptions related to the nature of the subject, namely, testing religions that claim miracles and divine revelations. The basic test is simple: Compare their claims with the truth of the Bible.
Testing the spirits, as commanded by the Bible, is not a theoretical exercise. It involves real people and real cases, including religious leaders and their teachings. This course, however, is a survey of the subject, and is not about specific individuals. Thus, while quoting accurately from individuals, the course avoids specifying authors and titles. The aim is not to single out someone particular for scrutiny, but to discuss biblical principles and to show comparisons at work. Modern quotes, offered as examples, are representative of many more like them, which can be found readily, using today’s search tools. You are encouraged to do your own research, especially looking under the surface of modern claims that you encounter.
Above all, take the Bible as your guide and your authoritative source for research. In the matter of miracles, let God’s Word define the true nature and purpose of signs, wonders and miracles. Compare human teachings with the true teachings of Scripture. Jesus, through the New Testament—the records of His inspired spokesmen—has already revealed the Faith “once for all” (Titus 1:3 cf. Galatians 1:6-9; Ephesians 3:5; 2 Peter 1:3). As you test the spirits, “all Scripture” holds the answers that you seek.
…the sacred writings are able to make you wise for salvation through faith in Christ Jesus. All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness, that the man of God may be complete, equipped for every good work (2 Timothy 3:15-17).
