Patrick Johnstone and Jason Mandryk suggest that "nominalism" is a major issue. They assert that "many traditionally Christian populations know nothing of a personal faith, true repentance, and a trust in the finished work of Christ for their salvation", and estimate that 1.2 billion people are "nominal and non-practising 'Christians'."
