In this book, Ryle introduces the cross of Christ based on the words of the Apostle Paul, the greatest Christian in history.
He emphasizes that the cross is the most important thing for us Christians.
The cross is not simply a matter of debate, but a subject we must understand correctly, and it is argued that everything we are depends on the cross.
“Heaven or hell, happiness or misery, life or death, blessing or damnation on the last day—the answer to all these questions hinges on the question, ‘How do you think and feel about the cross of Christ?’” In this book, he organizes his argument through three points: what the Apostle Paul did not boast about, what Paul did boast about, and why all Christians should think and feel about the cross as Paul did.
