When Jesus ate the Passover meal with His Jewish disciples in the upper room in Jerusalem, He took a cup of wine and said these profound words, "This cup is the new covenant in my blood which on your behalf is being poured out... for... the forgiveness of sins."  (Luke 22:20)

This New Covenant that Jesus spoke of was prophesied 600 years before by Jeremiah, when he foretold that Gold would cut a New Covenant with the house of Israel. Jesus was the representative Israelite with whom God cut this covenant, a covenant which was subsequently ratified by His death on the Cross and resurrection from the dead. Many people, both Jewish and Gentile, placed their trust in Jesus as the mediator of this New Covenant. What, however, did being in covenant with Jesus really mean for those early believers? What does it mean for people today to be in covenant with someone who lived some two thousand years ago? These are some of the questions which will be briefly touched upon in this book.
