"Memoirs of Stonewall Jackson", by his widow, Mary Anna Jackson, Louisville KY, 1895, pages 445-46 --

He delighted to enlarge on his favorite topics of practical religion, which were such as these: The Christian should carry his religion into everything. Christianity makes a man better in any lawful calling; it makes the general a better commander, and the shoemaker a better workman. In the case of a cobbler, or the tailor, for instance, religion will produce more care in promising work, more punctuality, and more fidelity in executing it, from conscientious motives; and these homely examples were fair illustrations of its value in more exalted functions. So, prayer aids any man, in any lawful business, not only by bringing down the divine blessing, which is its direct and primary object, but by harmonizing his own mind and heart. In the commander of an army at the critical hour, it calms his perplexities, moderates his anxieties, steadies the scales of judgment, and thus preserves him from exaggerated and rash conclusions. Again he urged that every act of man's life should be a religious act.

So Jackson was wont to say that the Bible furnished men with rules for everything. If they would search, he said, they would find a precept, an example, or a general principle, applicable to every possible emergency of duty, no matter what was a man's calling. There the military man might find guidance for every exigency. Then, turning to Lieutenant Smith, he asked him, smiling: 'Can you tell me where the Bible gives generals a model for their official reports of battles?' The lieutenant answered, laughing, that it never entered his mind to think of looking for such a thing in the Scriptures. 'Nevertheless,' said the general, ' there are such; and excellent models, too. Look, for instance, at the narrative of Joshua's battle with the Amalekites; there you have one. It has clearness, brevity, fairness, modesty; and it traces the victory to its right source — the blessing of God."
