Victoria Osteen crystalized Joshua 24:15 into a call to serve positive thinking. Instead of a call to turn from the Devil, sin, and self, and turn toward God, she spritzed the bible with the Osteen doctrine of positive thinking and calls her hearers to serve the idol of positive thinking.
14 “Now therefore fear the Lord and serve him in sincerity and in faithfulness. Put away the gods that your fathers served beyond the River and in Egypt, and serve the Lord. 15 And if it is evil in your eyes to serve the Lord, choose this day whom you will serve, whether the gods your fathers served in the region beyond the River, or the gods of the Amorites in whose land you dwell. But as for me and my house, we will serve the Lord.” Joshua 24:14-15 (ESV)
