A Very Brief Analysis
One way of looking at the Bible is that is principally the story of two covenants or agreements. The Old and New Testaments of the Bible are mainly concerned respectively with these two, called the Old and New Covenants. The words translated ‘Testament’ could equally if not better be translated ‘Covenant’.
The Old Covenant was an agreement between God and the ancient nation of Israel. Briefly if the people would follow all the ‘Laws of Moses’ (regulations including the Ten Words or Commandments given by God through Moses) then God would bless and protect them.
The prophet Jeremiah wrote of the coming of a ‘New’ Covenant thus:
“The days are coming,” declares the Lord,
“when I will make a new covenant
with the people of Israel
and with the people of Judah.
It will not be like the covenant
I made with their ancestors.”
These two Covenants are distinct and incompatible. The New Covenant is nothing less than the gift of eternal life to those who believe in the existence and sacrifice on their behalf of Jesus Christ the son of God.
