The theology of the church fathers, as well as Paul and even Moses, holds that mankind is encumbered by a sin nature passed down from Adam, common to everyone. The biblical evidence for this argument is plentiful. But modern American evangelicals often seem to miss this point, and instead emphasize the sinful behavior of the unsaved and saved alike. As a result many Christians are overwhelmed by the individual sins they see in their lives and wrestle constantly with the assurance of their salvation. What follows are preachers who evangelize in worship services, talk about “nailing down your salvation” and multiple baptisms. If we could understand our sin nature, we would be freed from this spiritual roller-coaster.
