This is the Spanish-language edition of John MacArthur's Hard to Believe. The book argues that the call of Christ has been softened into an offer of self-improvement, and sets the actual terms back in view: denying oneself, taking up a cross, counting the cost before building, and the narrow gate that few find. MacArthur contends that a message adjusted for easy acceptance produces converts who were never converted.

The book is written for professing Christians willing to examine the ground of their profession, and for pastors concerned that their preaching has grown accommodating. This edition serves Spanish-speaking readers and bilingual congregations. The entire text is in Spanish.
