However, any Christian who can "convert" any Jew is welcome to the attempt. As long as coercion or threat is not part of the attempt. Otherwise, we are each free to share what we feel is the good news of God's love.
However, Jews who are properly educated are more likely to shake a Christian's faith than the other way around.. and thus, its is normally bad form to put someone in a position where they must not share their thoughts so as not to offend one who is genuinely reaching out in love.
If all of the evil schemes of the past to force Jews into converting to this or that had been able to succeed, there would have been no Jews more than 2000 years ago. So, let go of this idea that animated the Inquisition and the Pogroms of the Czars.. it is unseemly.
That's your opinion. Jesus had a different one when he said "you shall be witnesses to Me in Jerusalem, and in all Judea and Samaria, and to the end of the earth" (Acts 1:8). He wanted for His followers to witness to the Jews!
This endeavor is a huge, and fruitless waste of time. Worse, as it is an attempt to pervert a relationship sanctified by God himself, it is one that carries consequence, as an evil act, and not one of salvation.
Read Acts, Chap 9. You’ll find the Lord’s opinion differs from your own.
The whole book of Acts is filled with fellowshiping with Jewish believers as Paul, Barnabas, Timothy and many others traveled throughout Asia. The first Christians were Jewish. The Bible says salvation is first for the Jew and then for the Gentile. There is no malice in what we do. And conversing with any knowledgable Jew would only strengthen my faith, not weaken it.
No human is able to convert another human to Christianity, for that is the work of God the Holy Spirit, but believers are able to witness to others about God’s Plan and are commanded to minister the Gospel to others.
Romans goes further in later books, say Romans 10-15, discussing how faith comes by hearing and hearing by the Word of God and that this is applicable not only for those uncircumcised, but even moreso for those circumcised.
It also clarifies that circumcision is not by the flesh but the circumcision of Abraham was by faith of the uncircumcised. Those Jews who have never believed by Christ are not saved, but those who are of the true olive tree, separated from the root and trunk are much more easily grafted back in than are the Gentiles.
