Don't disbelieve

I am studying the book of Hebrews. The book is written to the Jews but it helps every believer in Jesus.
This book will bridge the Old Testament with the New Testament.
I started to read the second chapter of this book, I was a little confuse then I prayed. I studied some more and this is my conclusion.
The author was explaining Jesus in this book. Jesus came for the salvation of the Jews and then the non-Jews.
Many Jews didn't believe in the Messiah because Jesus is the Messiah. God drew many Jews to his side but many Jews refused to believe the truth.
If a person refuses Jesus then there is no hope for them. This is true for a Jewish person, it is good that they are Jews but your nationality don't save a person.
It is faith in Jesus and the Jewish person needs to believe and follow Jesus.
If you are not a Jew, you need to believe in the Lord Jesus. Your job will not save you or being a good person. Everyone is a sinner that needs forgiveness. 
Everyone can be pardon, if they desire. The problem is that people love their sin and so reject the Lord.
Jesus came to this earth and proved that he was the Lord. He fulfilled hundred of prophecies and did miracles signs, so there is no excuse.
The world system seems so great but it is a dead end. So go on the forever road with Jesus.

Hebrews 2:1-4

 We must pay the most careful attention, therefore, to what we have heard, so that we do not drift away. ² For since the message spoken through angels was binding, and every violation and disobedience received its just punishment, ³ how shall we escape if we ignore so great a salvation? This salvation, which was first announced by the Lord, was confirmed to us by those who heard him. ⁴ God also testified to it by signs, wonders and various miracles, and by gifts of the Holy Spirit distributed according to his will.
