Christians: Do you want to convert Jews, or do you want them to rebuild the temple?

From what I understand the Christians are waiting for the Jews to rebuild the temple, some sort of biblical prophecy. So I was wondering if Christians are reluctiant to try and convert Jews because the Jews are part of God’s plan. Many evangelical Christians I have met profess their love for the Jews, I am not even sure they know why they love us? No one has ever been able to explain it to me. Maybe someone can answer that question also on this thread.
