The Triumph of Thomas Paine?

A recent Harris poll confirms what many of us suspect. America is not only secularizing, but Evangelical Christians are more and more apt to think and act like deists--echoing the view of Thomas Paine that morality is far more important than theology.
Some of the Harris poll numbers are not surprising (see read the raw numbers for yourself, Click here: While Most U.S. Adults Believe in God, Only 58 Percent are 'Absolutely Certain': Financial News - Yahoo! Finance)
For example, only 58% of those polled are absolutely certain of God's existence. That's down from 66% in 2003. This doesn't really surprise me, especially during a time of war and after the events of 911. In a world of continual violence and uncertainty, people become increasingly sceptical about God.
More revealing of the state of Christianity in America are the following numbers: "Do Jews, Christians and Muslims worship the same God?" "About half (51%) of all adults, including a majority of Catholics (63%), believe that Jews, Christians and Muslims all worship the same God. One-third (32%) believes they do not and 16 percent are not sure. On this question, as on the others, the views of Born Again Christians are different - a 54 percent majority believes they do not worship the same God and only 34 percent believe they do."
While a slim majority of evangelicals understand that the Triune God of Christianity is not Allah of Islam, more than one third of Christians polled do not understand this fundamental point of Christian theology.
And then when asked "How much control does God have over events on earth?" The result was that "less than one-third of all adults (29%) believe that God `controls what happens on Earth' (this includes 57% of Born Again Christians). A plurality (44%) believes that God `observes but does not control what happens on Earth.'" While a slight majority of Christians believe that God controls what happens, a deistic world-view is commonplace among Christians.
So, what can we say?
1). America is a nation of doubting deists who practice a moralistic religion which often times bears little, if any, resemblance to biblical Christianity.
2). Many Christians echo the views of a secularizing culture. The numbers show that many Christians are functional deists in terms of their views of God's relationship to the world. I guess people aren't really buying Rick Warren's "God has a purpose for your life" argument--but then, maybe they are. After all, according to Warren, God's purpose for your life is that you control your own destiny through the choices you make--and how is that different from a practical deism?
3). The default setting of many Christians and non-Christians alike is that everybody worships the same God. The differences among the religions stem from prejudice, or personal experience, or preference. This is no longer seen as a matter of competing truth claims. Many people see no possibility of one religion being true and the others false. It is all a matter of subjective and personal factors.
4). Given the depth of moralistic deism in the culture, it is no wonder that Reformed theology is hated in so many quarters (even in the churches).
5). Reformed Christians should see this as a moment of great opportunity. Our Christ-centered covenant theology (the mediator of the covenant is the Word made flesh) is a powerful antidote to moralistic deism. Therefore, let us be fully prepared to give to everyone who asks, a reason for the hope that is within (1 Peter 3:15).
