Q - Do Jews go to Heaven when they die if they do not believe in Jesus?

A - You need to check out Romans chapters 9-11 for answers to this question.

Paul in the beginning of this chapter is in anguish over his people, the Israelite, Jewish people that they have not believed in the Messiah, Jesus. Paul being a devout Jew was zapped by God on the Road to Damascus in Acts 9, and saw Jesus as the Risen Messiah. Paul did not become a Christian at that moment, he experienced the full expression of Judaism and became a follower of Jesus, he now followed the Messiah, the one he had been waiting for, the one revealed in the Hebrew scriptures, the one he had been persecuting. He wanted so badly for his own people to know this Messiah, because at this point many Jews did not in the Jesus movement.

Paul knew that Israel was still God's chosen people. The problem was that even within this people many did not follow God. Even within his own people they refused to believe in the Messiah, Jesus.

Romans 10:1-4 is the key for us. Even though Jews were devout for God, they refused to believe in Jesus, in his righteousness, they were still trying to find a different way. Paul then makes it clear that if they confess with their mouths and believe in their hearts that Jesus is Lord, they will be saved as well.

So do Jews go to heaven when they die? Only, if they believe that the Messiah Jesus is the fulfillment of their faith, in others words they are just like us gentiles or anyone else they must be born again to enter the kingdom of Heaven.

Acts 16:31
Believe on the Lord Jesus and you shall be saved.

Acts 4:12
And there is salvation in no one else; for there is no other name under heaven that has been given among men, by which we must be saved.
