Some things are non-negotiable. God's covenant with Israel is one of them. How could He have made Himself more clear?
He gave His oath to Abram, and reiterated it six more times to Abraham, to his son Isaac and to his grandson Jacob .On one occasion, "When God made His promise to Abraham, since there was no one greater for Him to swear by, He swore by Himself" (Heb.6:13).
Why did God speak so decisively? It was because He "wanted to make the unchanging nature of His purpose very clear to the heirs of what was promised, [so] He confirmed it with an oath' (Heb. ). God Who cannot lie bound Himself by an oath!
His covenant with
Israel was reiterated through Moses, repeated by the prophets and rehearsed by the psalmists. Jesus Himself affirmed it (Matt. ), Paul articulated it(Rom.9-11) and the gates of the New Jerusalem announce it forever (Rev. 22:11-12). God has chosen Israel as His covenant people.
What if Israel broke the covenant? What would then happen to them? Listen to these unmistakably clear truths: "Though I completely destroy all the nations among which I scatter you, I will not completely destroy you. I will discipline you but only with justice; I will not let you go entirely unpunished" (Jer. 30:11). God will completely destroy other nations, but He will not completely destroy Israel! He treats His people differently from other people; they are judged more strictly, but they will never be
No matter what Israel does, God will never forsake them as a distinct people .In Jeremiah 31:31-34, the Lord declares that He will make a new covenant with Israel and Judah. But He doesn't stop there. It's as if He's saying, "Now, don't get me wrong! Don't think that this new covenant means that I'm abandoning My people. No!"
This is what the LORD says, He who appoints the sun to shine by day, who decrees the moon and stars to shine by night, who stirs up the sea so that its waves roar
