Another thing which I taught is that a Christian can indeed have no doubt about his beliefs. Can you not say that there is no doubt that the Lord Jesus died on the cross and then He was resurrected from the dead?
I can also say that there is no doubt that those who believe will not perish but have everlasting life:
"For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life" (Jn.3:16).
Since there is no doubt about that I cannot understand why those in the Neo-MAD community say that the Jews who lived under the law were not saved by "faith" alone since they say that those Jews could not be saved apart from works.
Of course you are under no obligation to answer why those in the Neo-MAD community would say that but since you are one of the brightest among them perhaps you could share your wisdom with us as to why we should not believe that "faith" alone was sufficeient for their salvation?
