In 1862, during the Civil War, the Washington DC swamp (dews and damps), dimly lit through the fog, surrounded my the Union Army, the good news of their imminent victory was written fiery letters on their “burnished rows of steel” and the eventual victory of Christ over the forces of Satan. Our God is marching on - even now.
“I have seen Him in the watch-fires of a hundred circling camps, They have builded Him an altar in the evening dews and damps; I can read His righteous sentence by the dim and flaring lamps: His day is marching on.”
I have read a fiery gospel writ in burnished rows of steel: "As ye deal with my contemners, so with you my grace shall deal"; Let the Hero, born of woman, crush the serpent with his heel, Since God is marching on.
He has sounded forth the trumpet that shall never call retreat; He is sifting out the hearts of men before His judgment-seat; Oh, be swift, my soul, to answer Him! Be jubilant, my feet! Our God is marching on.
