Your quote is an example of why Jews find it difficult to completely trust Christian action. We hear two messages. The first is of love. The second is that we are doomed to Hell if we do not accept Jesus.
Well, to be honest, whenever someone says that, I just tell them to take it up with the Guy who said it. Yes, of course His message is “love”, but since when does “love” mean “let people do what they like when they like”? Parents love their kids and reign them in, guide them, sometimes punish them.
Surely, as a Jew, that’s far from an alien concept to you seeing as how God has repeatedly done that to Israel over the millenia.
