Nope. There are Jews who believe that Jesus is who He said He was. They'll make it.
What you need to realize is that it's not religion that saves, it's Jesus. It doesn't matter which religion you belong to if you have truly put your trust in Him to save you.
There are saved and unsaved in every religion.
I am not going to argue religion with you about what is right are wrong, that is exactly the reason for my initial post on this thread, so quit preaching!
