When all of Daniel's visions and prophecies are introduced together as one picture they teach thebalance between the Church (the children of the promise / God's eternal Purpose Rom.9:8-9, Gal.4:25-30, Note:v.28) and the Jews today (the children of the flesh Abraham Rom.2:28-28; 9;8).
God has only ONE PLAN and ONE PURPOSE. There is not one plan for the Jew and another for the Church. (Eph.3:1-12)
Daniel prophesied that "Messiah" would come (Dan.9:25). and God was faithful to His Word and Jesus, the Word (John.1:1-14, 18 / 1John.5:7), came to be the Messiah, He “came unto His own" (the Jews / House of Judah / the children of the flesh of Abraham John.1:11, Matt.15:24, Rom.9:8-9). This was to confirmthe covenant(Dan.9:27, Gal.3:17, Rom.15:8) that God, the Father (1John.5:7) made with Abraham, Isaac and Jacob (Gen.12:1-2; 15:1-21; 17:1-8, John.8:56-58, Heb.11:8-10 / Rev.21:9-10), Moses (Acts.3:22, Gal.3:24, Heb.10:1, Rom.3:21-31)and David (Acts.2:30, 1Chron.17- -17). This confirmation was to reconcileboth the Jew and the Gentile together in the Body of Christ / The Church / The "Israel of God" (Eph.2:1-19; 3:1-12, Gal.3:1-29; 6:15-16)This was rejected by the "children of the flesh" of Abraham, (the Jews) and they were "cut off" (Rom.11:20-25, Hosea.1:10,Matt.21:43) with the the promise of being graffed back in again (to the confirmation of the Covenant they rejected) "if they abide not still in unbelief." (Rom.9-11)
