The reason Stuart was bold is that he had an unshakeable faith in a sovereign, omnipotent Lord. He knew that nothing happens outside God's perfect will and that even bullets follow the path of the Lord. He went calmly into battle and he went calmly into death.
If the biographer ommitted Stuart's faith, it is a writing which reports only part of the man, an incomplete and suspect picture. I have no doubt that I will meet him worshipping the Lamb along with the other believers in the resurrection.
An excellent point. No doubt Lee, Davis and old Blue Light will also be there. Absent will be the atheist Lincoln and the scoffer's servants Sherman and Grant. The most fervent worshippers of the war criminals who fought a revolution to set aside our Constitution have always been atheist communists, socialists and the like. That hasn't changed since 1865. We see it proven here every time a thread is posted mentioning that war.
