Coulter was brief and perhaps you're reading more into her piece than what she intended. The Bible is clear that God places His effectual call on those Whom He chooses to save (i.e. be "born again.") From there man is regenerated, forgiven, converted and justified. As Christ's viceregents we merely share the meaning of the Bible, especially the soteriological issues, and God opens their eyes and hearts, leading them to repentance. This is basic theology and the failure of the church to teach this has allowed for the spread of Islam and other false religions and cults.
