Thus says the Lord: "If My covenant for day and night do not stand, and the fixed patterns of Heaven and Earth I have not established, then I would reject the descendants of Jacob and David My servant, not taking from his descendants rulers over the descendants of Abraham, Isaac, and Jacob.
"But I will restore their fortunes and will have mercy on them."
God had Jeremiah write specifically that He would never forget about the Hebrew peoples that have come down generationally from Jacob, the son of Isaac, the son of Abraham; and that David would be the direct ancestor of the rulers over this nation.
When the Day-and-Night cycle stops cycling; when the heavenly bodies, the stars & planets & the other objects in the sky, in space, stop doing what they do; only if they can disobey God's directions and rules for them; only then will God be able to disregard the Children of Israel.
Some people are teaching that God has substituted the Church for Israel and has given up on them; but these verses refute that notion.
Jesus said, "Other sheep I have, which are not of this fold: them also I must bring, and they shall hear My voice; and there shall be one fold and one Shepherd" (John 10:16), referring to the Gentiles who would hear the Gospel and be saved, forming the church, in addition to those of Hebrew/Jewish heritage.
(Abram [Abraham] was first called a "Hebrew" [ancient Habiru; Eberite, from Eber] in Genesis 14:13; and "Jewish" refers to the nation Judea, named from the tribe of Judah, who, with Benjamin, formed the Southern Kingdom of the divided Israel after King Solomon [I Kings 12:16, 20], and returned to the territory of Israel under the Persian kings Xerxes and his son Artaxerxes [see Daniel and Esther and Ezra and Nehemiah].)
So the "one fold" under "one Shepherd" is both Jews and Christians together as one family; recognizing Jesus as Messiah, Savior, and King.
Until Jesus returns, those Jewish people who become Christians (Messianic Jews) are part of the Church, and will be raptured with the rest of the church.
So Jesus, descendant of King David in the flesh, will rule from Jerusalem (Revelation 20:6), and all the promises to Israel will be fulfilled. God never forgets a promise: He knows what He's going to do, promises to do it, and He does it. Not always the way we think He will, but exactly as He said He would. Every time.
Jesus is coming soon.
Even so, come, Lord Jesus!
