Then the LORD said to him, “Know for certain that for four hundred years your descendants will be strangers in a country not their own and that they will be enslaved and mistreated there. But I will punish the nation they serve as slaves, and afterward they will come out with great possessions.
In American history slavery for blacks began and ended in 1618 – 1865.
Slavery ended around the world in:
1807 – Britain passes Abolition of the Slave Trade Act, outlawing British Atlantic slave trade. – United States passes legislation banning the slave trade, effective from start of 1808. 1811 – Spain abolishes slavery, including in its colonies, though Cuba rejects ban and continues to deal in slaves.
In the year 2018 from the year 1618 is 400 years. We are in the 400th year in our global nation. Could this mean anything concerning a people?
It does mean something in biblical writings in genesis 15:13-14. God sends Moses to get His nation so they could worship Him. The ordeal according to the bible got kind of messy but Gods word was fulfilled. He mentioned to Abraham that His nation would be in slavery but then released from harsh bondage. You can read the story of it in Exodus.
Now, although history repeats its self, there came later in the lineage of Gods nation a man name Jesus who would be The Christ, here after, the same lineage said to crucify Him. Thus now, we are in a new type of freedom – the liberty of the mind that we as a people now have is freedom in the grace of Christ Jesus. The Lord is now savior of the Church which is His body.
You can read more about this freedom in Paul writings starting with the book of Galatians. In the book of Galatians will explain the law and living by grace and love.
