This topic reminded me of an argument my mom and grandmother used to have. Mom would say that Jewish people had to believe in Jesus as their messiah to be saved. She quoted the John 14:6 passsage with the traditional fundamentalist interpretation. Grandma countered that since Jesus was fully God and fully man that Jewish people believed already in their messiah. They didn't need to say "I believe in Jesus as my saviour" to reach heaven. Mom and grandma spent many hours debating issues like that. Grandma wasn't so black and white in her views as mom.
I wasn't really trying to make a point just recalling a memory to share. FWIW
"Beloved let us tolerate one another. For tolerance is of God and everyone that tolerates is born of God and knows God. He that tolerates not, knows not God for God is tolerance." 1 John 4:7,8
