scandal of the evangelical Conscience

I've been reading the sobering book "The Scandal of the Evangelical Conscience" by Ronald J. Sider.
The book begins with this quote, "Evangelical Christians are as likely to embrace lifestyles every bit as hedonistic, materialistic, self-centered, and sexually immoral as the world in general." (Michael Horton)
Sider goes on to quote site a study by George Barna who found that the percentage of born-again Christians who had experienced divorce was slightly higher than that of non-Christians.
In 1968, the average church member gave 3.1 per cent of their income- less than a third of a tithe (10%). That figure dropped every year through 1990 and then recovered somewhat in to 2.66%. Sider notes, "as we got richer and richer, evangelicals chose to spend more and more on themselves and give a smaller and smaller percentage to the church. Today, on the average, evangelicals in the US give about two-fifths of a tithe. "
What about pornography? Citing a recent survery in Leadership magazine, the percentage of Christian men involved in pornography is not much different than that of the unsaved.
When it comes to physical abuse in marriage - it seems that Christians are dead even with the general public, according to Side.
In 1990, the number of unmarried couples living together jumped higher in the Bible belt than in the nation as a whole. (In Arkansas = 125% higher!) In our sexual behavior, 26% of traditional evangelicals do not think that premartial sex is wrong.
Sider comments, "The contrast between contemporary Christians behavior and New Testament teaching and practice is stark. The extent of our scandalous failure today becomes clear only when we recall what Jesus expected and the early Christians experienced."
Let this soak in. This post will be continued . . .
