The land of PROMISE.
No one can expect heaven without God's free gift. It will matter not at all to those who refuse the gift of eternal life if God gives the land to the Jews or not. What the future holds for the Jews and the land is God's doing. So what is God up to regarding Israel today? Why the controversy of Zion? Isa 34:8
The covenant of the land is a guaranteed and unilateral covenant, a gift and a promise that the land will belong to the Jews for 1000 generations. If a generation is only TEN years this promise is enforce for 10,000 years!
“O ye seed of Abraham his servant, ye children of Jacob his chosen. He is the LORD our God: his judgments are in all the earth. He hath remembered his covenant for ever, the word which he commanded to a thousand generations. Which covenant he made with Abraham, and his oath unto Isaac; And confirmed the same unto Jacob for a law, and to Israel for an everlasting covenant: Saying, Unto thee will I give the land of Canaan, the lot of your inheritance:” (Psa 105:6-11, KJV)
God does command Abram "walk before me, and be thou perfect." But God does not say "if you do this I will give you the land of Canaan." The command precedes the promise and gift of the land. There is no IF / THEN. God is essentially saying "Do this and I will..." He is not saying..."If you will do this then I will... " The IF / THEN covenant comes later via Moses to Israel. Israel was exiled temporarily from the land but restored from Babylon after 70 years. She was exiled in 70 AD because she rejected her Messiah. But this again is not a recinding of the promise of the land now only around 4000 years old.
“For if the casting away of them be the reconciling of the world, what shall the receiving of them be, but life from the dead? For if the firstfruit be holy, the lump is also holy: and if the root be holy, so are the branches.” (Rom 11:15-16, KJV)
No one, Jew or Gentile, will enjoy the gifts and inheritance is given by God to them in except they have faith in the Lord Jesus Christ. This is the issue and the resolution of the controversy of Zion (the land) and the Jews cannot be separated.
No one in heaven's eternal comfort will be unhappy if God keeps his promise of the land to Abraham and his descendants. Hell will likely be eternally bitter over the matter. Instead of judging Israel's inability to walk today before God blameless we might do well to remember the impossibility of inheriting any gift, promise or reward from God while in the condemnation of unbelief. John 3:18 -21.
God did not send Jesus into the world to condemn it but that the world through him might be saved. John 3:17
“For I am not ashamed of the gospel of Christ: for it is the power of God unto salvation to every one that believeth; to the Jew first, and also to the Greek. For therein is the righteousness of God revealed from faith to faith: as it is written, The just shall live by faith.” (Rom 1:16-17, KJV)
Make sure your righteousness is of faith trusting God's word and promises.
