"The Jews need conversion."
Only in the minds of those who worship false gods.
Jews are quite happy worshiping the ONE True God, the same God they worshipped LONG before other religions were invented.
Trying to acquire Jews' souls, either through niceness or torture, and even after death (diabolical Mormon practice) means you will have to account for that - to the God of Israel.
Worship YOUR god; let others worship THEIR God - without interference.
Everyone needs Jesus. Everyone.
Saying the truth I prevent no one from doing whatever they want. You just do not want me to be able to say the truth.
If the Jews don’t need Christ, then who is preparing the annual sacrifice for the atonement of their sin by the most strict sacrificial system?
