During the Tribulation, God will return to deal with Israel, so yes, everything in Hebrews to Revelations are directed TO the Jews.
Only for the Jews? That is insane. Look at some of the scriptures you will be ignoring:
Heb 4:12 For the word of God is quick, and powerful, and sharper than any twoedged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart.
Heb 11:1 Now faith is the substance of things hoped for, the evidence of things not seen.
Jas 1:13 Let no man say when he is tempted, I am tempted of God: for God cannot be tempted with evil, neither tempteth he any man:
Jas 1:14 But every man is tempted, when he is drawn away of his own lust, and enticed.
Jas 1:15 Then when lust hath conceived, it bringeth forth sin: and sin, when it is finished, bringeth forth death.
1John 2:3 And hereby we do know that we know him, if we keep his commandments.
1John 2:4 He that saith, I know him, and keepeth not his commandments, is a liar, and the truth is not in him.
1John 2:5 But whoso keepeth his word, in him verily is the love of God perfected: hereby know we that we are in him.
1John 2:6 He that saith he abideth in him ought himself also so to walk, even as he walked.
1John 2:7 Brethren, I write no new commandment unto you, but an old commandment which ye had from the beginning. The old commandment is the word which ye have heard from the beginning.
1John 2:8 Again, a new commandment I write unto you, which thing is true in him and in you: because the darkness is past, and the true light now shineth.
1John 2:9 He that saith he is in the light, and hateth his brother, is in darkness even until now.
1John 2:10 He that loveth his brother abideth in the light, and there is none occasion of stumbling in him.
1John 2:11 But he that hateth his brother is in darkness, and walketh in darkness, and knoweth not whither he goeth, because that darkness hath blinded his eyes.
1John 4:1 Beloved, believe not every spirit, but try the spirits whether they are of God: because many false prophets are gone out into the world.
1John 4:2 Hereby know ye the Spirit of God: Every spirit that confesseth that Jesus Christ is come in the flesh is of God:
1John 4:3 And every spirit that confesseth not that Jesus Christ is come in the flesh is not of God: and this is that spirit of antichrist, whereof ye have heard that it should come; and even now already is it in the world.
2John 1:4 I rejoiced greatly that I found of thy children walking in truth, as we have received a commandment from the Father.
2John 1:5 And now I beseech thee, lady, not as though I wrote a new commandment unto thee, but that which we had from the beginning, that we love one another.
2John 1:6 And this is love, that we walk after his commandments. This is the commandment, That, as ye have heard from the beginning, ye should walk in it.
Rev 1:11 Saying, I am Alpha and Omega, the first and the last: and, What thou seest, write in a book, and send it unto the seven churches which are in Asia; unto Ephesus, and unto Smyrna, and unto Pergamos, and unto Thyatira, and unto Sardis, and unto Philadelphia, and unto Laodicea.
All those scripture have to do with New testament doctrine and how is it invalid all of a sudden to gentile believers if it is addressed to Jews and even in Revelation it talks to the Seven churches which are in gentile cities. Did God save the Jews with a different kind of salvation no,
because salvation is of the Jews:
John 4:22 Ye worship ye know not what: we know what we worship: for salvation is of the Jews.
We all know certain scripture speak about the Jews ,but
we would not be able to interpret the prophecy of Revelation concerning the Tribulation and the Jews if God did not want us to. We are. So God wanted us to read and understand it.
Please ,listen to scripture ,not know it all theologians that keep coming up with the awful teachings that contradict scripture:
2Tim 3:16
All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness:
