Don't bring GOD into the equation. Slavery was wrong, but the Bible does not prohibit it. As a matter of fact, it gives instructions on how slaves were to be treated. The Confederacy lost due to overwhelming manpower and resources that were used against it. "God" didn't condemn the South due to slavery.
Funny that you don't know that the South has more devout evangelical Christians than any other part of the country.
Again...Slavery is morally wrong, but not from a biblical standpoint.
In the Civil War (or the War of Northern Aggression as we refer to it here in Virginia), slavery was the pretext for the war. The real issue of the war was secession. The Constitution didn't address whether or not a state could leave the Union if its citizens so wished. Lincoln abused federal power and forced secession of the southern states. The question was settled by armed combat instead of in the courts.
If Lincoln had not forced the issue, slavery would have gone away within a few decades as a result of the Industrial Revolution. Every "advanced" ancient society (Egypt, Rome, etc.) used slaves for heavy labor because mechanization didn't exist. Industrialization lowered costs and would have made slavery the more expensive option.
