In spite of the fact that critics have found valid problems with some of the questions asked in the Pew Forum’s September 2010 “U.S. Religious Knowledge Survey,” for example, questions dealing with world religions, especially since world religions’ foundational tenets, practices, history, and famous religious figures have nothing to do with what actually is written in Christians’ Holy Bible, the sad truth is that this survey is spot on about many American Christians, in this 21st-century. Truly, too many of these Christians are living in both a biblically and a doctrinally illiterate culture.
Apostle Paul advises the believers in the churches of Galatia that they must give rigorous attention to doctrinal clarity, and that they also must remain faithful to the true Gospel he taught them, if they are to have any hope of being able to avoid losing their faith, in such a time as this, or have any hope of being able to avoid permanently falling away from their faith (becoming apostates). This advice, thus, is useful for modern-day believers, as well!
