Yes, the first Civil War was over slavery. No matter how you slice it, had there not been slavery in the South there would not have been a Civil War. The lives lost in the War was God’s judgement on the country. Judgement is coming again. The millions of aborted babies requires it. It will be another bloody civil war. When RvW is overturned and abortion ruled to be unconstitutional, states like CA and NY will secede and dare Trump to send in troops to shut down abortion clinics and enforce the ban. Trump won’t back down. THIS IS THE REASON he has been anointed, protected and preserved as POTUS.
If there had not been people in the South, there also wouldn't have been a civil war. If the South was barren, and the people poor, there also would not have been a civil war.
You are misidentifying the actual dispute of the civil war as being about slavery instead of being about money. The War was fought because the South was going to take 230 million dollars per year out of the New York and Washington DC economy, just for starters.
The lives lost in the War was God’s judgement on the country.
So why didn't God see fit to judge the 13 slave owning colonies when they tried to gain independence from England, which had banned slavery? Why did God wait "four score and seven years" to finally decide that slavery needed to go?
Were the Founders not guilty of exactly the same thing as the Confederates?
