The NT does not say that all of the Lord's promises have been fulfilled.
Anyone in their right mind KNOWS that this prophecy concerning the "land" which the Lord gave to Jacob has not been fulfilled:
"Behold, I will take the children of Israel from among the heathen, whither they be gone, and will gather them on every side, and bring them into their own land...And they shall dwell in the land that I have given unto Jacob my servant, wherein your fathers have...Moreover I will make a covenant of peace with them; it shall be an everlasting covenant with them: and I will place them, and multiply them, and will set my sanctuary in the midst of them for evermore. My tabernacle also shall be with them: yea, I will be their God, and they shall be my people" (Ez.37:25-27).
Here we read that the Lord will set His sanctuary in the midst of the Israelites for ever. And the Israelites "shall dwell in the land that I have given unto Jacob.." Therefore, in the future the Lord will set His sanctuary in the midst of the children of Israel for evermore at the time they will dwell in the land that God gave to Jacob.
