***Such as Judaism?***
John 14:6
Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me.
This is the heart of the Gospel...the good news of Christ the Saviors victory over death.
Acts 2:21
And it shall come to pass, that whosoever shall call on the name of the Lord shall be saved.
An open invitation to all.
The 12 apostles, all Jewish disciples of the Jewish Jesus Christ told many Jews this exact Gospel.
I think you’re on shaky ground when you conclude that Jews are/will be damned.
