Jews don’t seek convert people because Judaism is not a missionary faith; the main reason for this is down to their theology which doesn’t necessitate the need to be Jewish in order to enter Heaven. This is from the Talmud:
“The righteous of the nations have a share in Olam Ha-Ba (heaven).”
This is at odds with the Christian doctrine that only by accepting Jesus as your saviour can you enter the Kingdom of Heaven and the grim alternative, that if you don’t accept Jesus you will suffer internal damnation. Therefore it is the duty of a Christian to go out and convert all non believers to Christianity. It is a teaching that has lead to some of the worst acts of intolerance, not only towards non Christians but towards those Christians whose faith was deemed heretical.
You forget that was Jesus’s original position as a Jew. That his disciple preach only to the Jewish people.
Matthew 15:24 He answered, “I was sent only to the lost sheep of Israel.”
Matthew 10:23, NIV: When you are persecuted in one place, flee to another. Truly I tell you, you will not finish going through the towns of Israel before the Son of Man comes.
But all this changed after Jesus was given all authority over heaven and earth.
The Great Commission
Matthew 28:16 Then the eleven disciples went to Galilee, to the mountain where Jesus had told them to go. 17 When they saw him, they worshiped him; but some doubted. 18 Then Jesus came to them and said, “All authority in heaven and on earth has been given to me. 19 Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, 20 and teaching them to obey everything I have commanded you. And surely I am with you always, to the very end of the age.”
The Jews feel betrayed by their messiah Jesus. But they could only crucify Jesus once.
Christianity can only benefit from Jesus’s return. Should Jesus be crucified on every subsequent return by the Jews. Christianity will see that as another opportunity to renew their vows.
Jesus taught the concept of dead Jews like him could forgive sins and offer salvation to the gentiles. Any wonder the Jews rejected Jesus’s eaching to protect Jews from becoming daily sacrifices.
