According to the Apostle to the GENTILES and in this context... it's IGNORING the mystery pertaining to ISRAEL.
So please explain what you think "the mystery" is.
This is what I believe the mystery is in part.....
Romans 11 KJV
30 For as ye in times past have not believed God, yet have now obtained mercy through their unbelief:
31 Even so have these also now not believed, that through your mercy they also may obtain mercy.
32For God hath concluded them all in unbelief, that he might have mercy upon all.
Who told you that the nation of Israel shall be saved by animal sacrifices ?
What do you believe about How Israel will come to believe?
What do you believe about the 1000 reign?
