I don't always agree with the conclusions pollster George Barna draws from his research, but here is something he says that is right on. Barna says, "People do not have an accurate view of themselves when it comes to spirituality. American Christians are not as devoted to their faith as they like to believe. They have positive feelings about the importance of faith, but their faith is rarely the focal point of their life or a critical factor in their decision-making. The fact that few people take the time to evaluate their spiritual journey, or to develop benchmarks or indicators of their spiritual health, facilitates a distorted view of the prominence and purity of faith in their life."
This is why we need to be relentlessly biblical. "Positive feelings" about "faith" do not a Christian make.
