As expressed by Lincoln, what are two central ideas in this sentence from this paragraph?

Slavery is an inevitability continued or discontinued at God's will, and God's power must be honored even when punishment causes suffering.

Explanation:

1. Slavery, which was a social and economic system based on the use of slaves as labor and its entire process through history. It was precisely President Abraham Lincoln who succeeded in abolishing slavery through the Proclamation of Emancipation.

2. The terrible war referred to is the Civil War that took place in the United States by the northern states and the segregated states of the South, where slavery was the trigger for that incident. By asking the question if any deviation from the divine attributes attributed to God could be discerned, Lincoln on more than one occasion could show himself as a man of faith and a believer in God, for which he mentioned it in many of his famous speeches and phrases.
