Are all monotheistic religions in Christ?
No. Monotheistic religions that reject Jesus Christ as their foundation are not in Christ. Scripture presents Jesus Christ as the one and only foundation for faith, and it alone is confirmed by hundreds of fulfilled prophecies. Other religious books cannot match that prophetic accuracy.
Les teaches that all the other religions of the world know nothing of Jesus Christ as their foundation, and this is where believers must be adamant. He grants that this is narrow—'this is a narrow book.' When people ask whether the Koran and other books are all wrong, Les responds by asking if any other book predicted things thousands of years in advance and they happened. The Bible is the only one; prophecy has secured its accuracy. He notes that 360-some individual prophecies concerning Christ's first coming were all fulfilled completely, so it is inconsistent to say the rest may not be true. Paul said he was a master builder who laid the foundation, and that foundation is Jesus Christ—the one and only foundation for what we believe. Therefore, monotheistic religions without Christ as their foundation are not in Christ.
