God reveals His intentions

The Abrahamic Covenant is a progressive covenant by God in which His blessings are progressively brought upon all peoples. In this age, believers have been placed "in Christ," and have been made partakers of the New Covenant with its blessings of the forgiveness of sins and indwelling Holy Spirit. In the messianic kingdom, the blessings of the Abrahamic Covenant will be extended further, so that we have a redeemed world united in faith and service to Jesus Christ, and thereby experiencing justice, righteousness and peace.

Jesus, who has fulfilled the prophets, and completed prophecy; who is the way, the truth, and the life; and the founder, mediator, and governor of His own kingdom.

Old Testament prophecy often had not a single but triple fulfilment – past, present and future.
i. The posterity fulfilment was an immediate or historical fulfilment in the life of the nation of Israel.
ii. The land is an intermediate or gospel fulfilment in Christ and His church.
iii. The blessing will be an ultimate fulfilment in the new heaven and new earth.

To sum up, Jesus has fulfilled, is fulfilling, and shall completely fulfill the entire Old Testament. The Old Covenant is to the New what promise is to fulfillment. He has ushered in the new era of salvation in the flow of God’s plan of salvation begun in the Old Testament. All the promises of God are absorbed in Christ’s life and being. He becomes the fulfillment of the Old Testament without destroying it.
