The purpose of this series is to show that Bible covenants cause the Old and New Testaments to have unity. The Old and New Testaments, are the revelation of One God to a people He is calling out of this world. One can easily see the truth of that statement if he/she looks at God’s plan of redemption via the covenants He entered into with mankind in order to restore him, to redeem him. Excerpts from John Calvin’s Institutes of the Christian Religion will be used to support my purpose statement.
