Are you thinking this nullified God's covenant with Abraham? I don't.
Abraham showed his faith in God, but that doesn't mean that God promised in vain.
Much love!
I would suggest that the physical land was but a step toward the ultimate goal, not the goal itself. Abraham recognized that, and Jesus affirmed that recognition when He said, Abraham saw my day and was glad. The long term plan of God, the carrying out of His ultimate purpose for mankind, has gone beyond one nation's occupation of a small plot of land in the Middle East. I've been busy this past week, so didn't get to completing my study of the present Israel of God, but it's Sabbath now, and I will be working on it this afternoon. It will answer who is Israel now, and why. At least from how I see the Biblical perspective.
As for your comment previously, (or was it Hiddens?) that only some of God's promises are conditional (in context of the re-establishment of Israel) I would place the differentiation between conditional and unconditional at the same place as the difference between salvational prophecy and apocalyptic prophecy. Israel's salvation and restoration was always on the condition of a change of heart. Deuteronomy 30 which follows the list of blessings and curses that God revealed would be the inevitable consequence of their choice between life and death, or obedience and rebellion, speaks of God's willingness to forgive and restore them. His determination to have compassion on His people, but that compassion was always conditional on Israel's heart attitude. Always. No-where in Israel's recent history as it pertains to the current situation in Palestine, is there any hint that they,
as a nation, have met the conditions that would prompt God's compassion on their behalf.
Deut.30:1 ¶ And it shall come to pass, when all these things are come upon thee, the blessing and the curse, which I have set before thee, and thou shalt call them to mind among all the nations, whither the LORD thy God hath driven thee,
2
And shalt return unto the LORD thy God, and shalt obey his voice according to all that I command thee this day, thou and thy children, with all thine heart, and with all thy soul;
3
That then (if the above condition is met) the LORD thy God will turn thy captivity, and have compassion upon thee, and will return and gather thee from all the nations, whither the LORD thy God hath scattered thee.
4 If any of thine be driven out unto the outmost parts of heaven, from thence will the LORD thy God gather thee, and from thence will he fetch thee:
5 And the LORD thy God will bring thee into the land which thy fathers possessed, and thou shalt possess it; and he will do thee good, and multiply thee above thy fathers.
6 And the LORD thy God will circumcise thine heart, and the heart of thy seed, to love the LORD thy God with all thine heart, and with all thy soul, that thou mayest live.
7 And the LORD thy God will put all these curses upon thine enemies, and on them that hate thee, which persecuted thee.
8 And thou shalt return and obey the voice of the LORD, and do all his commandments which I command thee this day.
