Jesus is the King, we are His Israel, He is our Perfect David, and He has already fully fulfilled all sacrifices (Hebrews 10:14 "For by one offering he hath perfected for ever them that are sanctified")... and, really, when you look at it, there's not much more to say.
According to the Apostles, THE CHURCH is "God's Israel" -- not some Socialist Nation-State of Christ-Rejectors who persecute the Jews for Jesus, for crying out loud!
They AREN'T "God's Israel", and thinking otherwise detracts from their True spiritual needs -- they're a bunch of God-Hating, Christ-Rejecting Jews who need to be Prayed For and Converted!!
And what Institution is equal to the task of converting even the God-Haters and the Christ-Blasphemers? Only the Institution ordained and sanctified by Jesus Christ himself -- GOD'S ISRAEL, the Christian Church, marching forth with Word and Sacrament.
Best, OP
Afterward shall the children of Israel return, {{WE ARE RIGHT HERE TODAY}} and seek the LORD their God, and David their king; and shall fear the LORD and his goodness in the latter days.
Hosea 3:4-5 =====
OP, is the Church the "children of Israel" in this passage? Sure sounds like ethnic Jews since they had a king, prince, etc. at one time and then were without it.
What's the "many days" reference between the children of Israel (the Church in your eschatology). When did the Church ever lose their King, prince, priesthood, etc. Sure seems to me the children of Israel speaks of the physical seed of Abraham.
