If you’re advocating getting yourself under the Mosaic Law; good luck . . but, be prepared to keep it ALL . . every jot, every tittle, every dietary requirement, everything . . because if you break one jot, or one tittle; or ever have broken one jot or one tittle, you are then guilty of breaking the WHOLE LAW - as bad as any adulterer, pornographer or politician. God’s GRACE, through the blood of Christ is the ONLY way, the only door.
Okay...well technically they were all Hebrews thru Jacob Isaac and Abraham...if you really want to put the matter thru the technicality strainer and Christians have been made spiritual Hebrews and children of Abraham via the Spirit of Adoption...there-bye fulfilling the promise to Abraham that the gentiles would be part of the inheritance.
Further, we were strangers and foreigners as far as the Law of Moses was concerned (Gentiles). It is only through Christ that we can be grafted into the olive tree that is Israel. We are wild olive branches; they are the natural branches. The replacement theology that dispossesses the Jews had better think again. - Again, I don’t know anything about this Hoggard guy. - I do like to watch Irvin Baxter on End of the Age on the Church Channel; his programs are really good - doesn’t sound anything like Hoggard.
I don't mean to correct you, and I don't want to take the time to study it perfectly, but I think that Levi was set apart - He didn't get an inheritance, except a portion of the inheritance of each of the tribes... So Levi was scattered throughout Judah and Israel... I don't think Levi is counted with the House of Israel, even though a portion went into the diaspora with them (as can be noted by the identifiable Cohenim genes in far-flung places).
That doesn't go against your main point btw, as many were found to be righteous by YHWH prior to the crucifixion. I don't think that means they kept the law perfectly, mind you... but rather by faith (as is always the case)... Along with trying their best to keep the law, and repentance where needed...
