A biblical worldview, as defined by the Barna study, is believing that absolute moral truth exists; the Bible is completely accurate in all of the principles it teaches; Satan is considered to be a real being or force, not merely symbolic; a person cannot earn their way into Heaven by trying to be good or do good works; Jesus Christ lived a sinless life on earth; and God is the all-knowing, all-powerful creator of the world who still rules the universe today.
Barna required a study to discover what Catholics and Jews have believed and taught for ages?
