Biblical illiteracy has become an epidemic across America. People, sadly including many professing Christians, simply don’t know what the Bible teaches and often hold to unbiblical or even heretical beliefs. For example, a recent study found that a mere 10% of Americans have a biblical worldview (despite 70% of Americans claiming the label of Christian). And the biblical teachings that the study considered part of a “biblical worldview” were the most basic of biblical beliefs, such as the personhood of the Holy Spirit or the existence of Satan. This study is a sad testament to the state of the American church.
