When Grant was fighting his last campaign with cancer at Mount McGregor, General O. O. Howard, who had honestly won the title "The Christian Soldier," came to call on him.
He spoke for a time to Grant about some of the battles & campaigns of the war in which both men had played so illustrious a part.
Grant listened for a time & then, interrupting him, said, "Howard, tell me what you know about prayer."
Face to face with death and the unknown, the question of prayer was of greater interest to the dying soldier than the reminiscences of his battles.
Phil 4:6 (NIV): “Do not be anxious about anything, but in every situation, by prayer and petition, with thanksgiving, present your requests to God.”
“Of all things, guard against neglecting God in the secret place of prayer.” - William Wilberforce.
