Avery Foley of Answers in Genesis has the report:
Despite the growing number of religiously unaffiliated people, over 70% of Americans still claim to be Christians. Yet only 46% of US adults would say they have a biblical worldview. But do almost half of Americans really possess a biblical framework through which they view the world?
Survey: Do You Think and Act Biblically?
The American Culture and Faith Institute (ACFI) recently conducted nationwide surveys of over 6,000 people to determine how many Americans have a biblical worldview—that is, how many Americans use the Bible as their filter for reality, to determine right from wrong, and to shape their beliefs, attitudes, and actions. Research shows that nearly half of Americans believe they have a biblical worldview, but, not surprisingly, this in-depth ACFI study showed that a substantially smaller number than 46% actually hold to basic biblical beliefs and practice what God’s Word teaches.
