What exactly is a "Biblical" worldview?

George Barna defines "biblical worldview" as:
"[B]elieving that absolute moral truths exist; that such truth is defined by the Bible; and firm belief in six specific religious views. Those views are that

  1. Jesus Christ lived a sinless life;
  2. God is the all-powerful and all-knowing Creator of the universe and He stills rules it today;
  3. Salvation is a gift from God and cannot be earned;
  4. Satan is real;
  5. a Christian has a responsibility to share his/her faith in Christ with other people;
  6. and the Bible is accurate in all of its teachings."
