You teach replacement theology.It of course was written to ALL... believers of The New Covenant Jesus Christ!
Heb 8:6-8
6 But now hath He obtained a more excellent ministry, by how much also He is the mediator of a better covenant, which was established upon better promises.
7 For if that first covenant had been faultless, then should no place have been sought for the second.
8 For finding fault with them, He saith, "Behold, the days come, saith the Lord, when I will make a new covenant with the house of Israel and with the house of Judah:"
KJV
Of course, Judaism doesn't recognize The New Covenant, nor The New Testament Scripture like the above, which is about Jesus Christ The Mediator of a better Covenant, The New Covenant.
DO YOU BELIEVE THE NEW COVENANT IS JESUS CHRIST?
I knew it all along.
