Ron Sider (a Professor of Theology at Eastern Baptist Theological Seminary and author of a GREAT book called "Rich Christians in an Age of Hunger") has an article in Christianity Today called "The Scandal of the Evangelical Conscience," asking why evangelicals don't live what they preach?
[T]he polls showed that members of the movement divorced their spouses just as often as their secular neighbors. They beat their wives as often as their neighbors. They were almost as materialistic and even more racist than their pagan friends.
By their daily activity, most "Christians" regularly commit treason. With their mouths they claim that Jesus is Lord, but with their actions they demonstrate allegiance to money, sex, and self-fulfillment.
The findings in numerous national polls conducted by highly respected pollsters like The Gallup Organization and The Barna Group are simply shocking. Divorce is more common among "born-again" Christians than in the general American population. Only 6 percent of evangelicals tithe. White evangelicals are the most likely people to object to neighbors of another race. Josh McDowell has pointed out that the sexual promiscuity of evangelical youth is only a little less outrageous than that of their nonevangelical peers.
American Christians live in the richest nation on earth and enjoy an average household income of $42,409. The World Bank reports that 1.2 billion of the world's poorest people try to survive on just one dollar a day. At least one billion people have never heard the gospel. The Ronsvalles point out that if American Christians just tithed, they would have another $143 billion available to empower the poor and spread the gospel. Studies by the United Nations suggest that just an additional $70–$80 billion a year would be enough to provide access to essential services like basic health care and education for all the poor of the earth. If they did no more than tithe, American Christians would have the private dollars to foot this entire bill and still have $60–$70 billion more to do evangelism around the world.As evangelicals we claim to embrace the Bible as our final authority.
One of the most common themes in the Scriptures is that God and his faithful people have a special concern for the poor. Why this blatant contradiction between belief and practice?
