How does one grasp the essence of the New Testament? Simply put, the New Testament is about promises fulfilled in Jesus.
Jesus himself understands the out-working of his ministry as the fulfillment of Israel’s promises concerning the Messiah (Luke 24:27). The New Testament is an entire Testament written to fulfill the promises left unfulfilled in the Old Testament. Thus, the New Testament forms the second part of the Christian Scriptures. One should be careful when reading the New Testament to see how many quotations and allusions there are to the Old Testament. The New Testament was not written in isolation from the Old Testament. The message of the New Testament is the fulfillment of the Old Testament promises concerning Jesus.
It is also important to think through the various sections of the New Testament and their unique perspective and emphasis on Jesus. Each section points in a unique way to show how Jesus fulfills God’s promises.
