The promises to Abraham and Israel were fufilled. The nations are blessed in Christ. The Seed has come, who is Christ Jesus, the land is fulfilled and all those of Israel who believe in Christ are seeking a Heavenly land, a city built by God. See Heb 11; Gal 3 & 4.
Neh 9:8 And Thou didst find Abraham's heart faithful before Thee, and didst make a covenant with him to give him the land of the Canaanite, of the Hittite and the Amorite, of the Perizzite, the Jebusite, and the Girgashite-- to give it to his descendants. And Thou hast fulfilled Thy promise, for Thou art righteous.
Jer 11:5 "in order to confirm the oath which I swore to your forefathers, to give them a land flowing with milk and honey, as it is this day." Then I answered and said, "Amen, O LORD."
Heb 11
8 By faith Abraham, when he was called to go out into a place which he should after receive for an inheritance, obeyed; and he went out, not knowing whither he went. 9 By faith he sojourned in the land of promise, as in a strange country, dwelling in tabernacles with Isaac and Jacob, the heirs with him of the same promise: 10 for he looked for a city which hath foundations, whose builder and maker is God. ... 13 These all died in faith, not having received the promises, but having seen them afar off, and were persuaded of them, and embraced them, and confessed that they were strangers and pilgrims on the earth. 14 For they that say such things declare plainly that they seek a country. 15 And truly, if they had been mindful of that country from whence they came out, they might have had opportunity to have returned. 16 But now they desire a better country, that is, an heavenly: wherefore God is not ashamed to be called their God: for he hath prepared for them a city.
