What Happened on the Cross offers a new and biblical understanding of how salvation was accomplished upon the cross, showing that the Penal Substitution view, common since the 1500s, does not have a biblical basis, and also showing that the Christus Victor understanding is inadequate. The book is founded upon the understanding that Jesus Christ is the Second Adam, and that is the foundation of how we are to understand how salvation was accomplished. Both the shedding of blood and death were essential in the accomplishment of salvation, and What Happened on the Cross shows why these were essential. Using over 740 Scripture verses to make its argument, the book gives a comprehensive picture from Genesis to Revelation of the many aspects involved in the accomplishment of salvation--above all showing clearly that the cross had nothing to do with "punishment for sins"--our sins were never punished upon the cross, rather, our sins were forgiven. Understanding how salvation was accomplished upon the cross, and that it was about forgiveness, not punishment, both exalts God and his greatness, demonstrates his perfect love and justice, as well as liberates our hearts towards him.
