I have a number of Jewish friends who might find his comments a bit insulting.
Of course they would be insulted. But, it doesn’t mean he is wrong if you really believe in the words of Jesus Christ:
“I am the Way, the Truth, and the Life; no man cometh unto the Father, but by Me...”
Why would they find his comments insulting?
The implication is that your friends are religious Jews - their very existence (as religious Jews) is a statement of their belief that my religion, Christianity, is false. (Just as my existence as a believing Christian is a statement of my belief that their religion is false.)
I am not insulted by their existence, nor by their beliefs, nor even if they were to tell me that my religion is false. I am mature enough, and sophisticated enough to not be insulted by another man’s non-Christian faith. That he should assert the truth of his faith, and the falsity of mine is no occasion to take offense. I would, at the least, admire the man’s contention for his belief.
Are your friends immature, or are they unsophisticated? How do they react to the fact that Jesse Jackson, Al Sharpton and Louis Farrakhan are democrats? Or that the liberals of the 30s supported Hitler? Or that the socialist Soviets persecuted the Jews? Or that the KKK was comprised mostly of democrats? Or the abandonment of Israel by the democrats? If they remain democrats in light of that knowledge, they are hypocrites if they tell you they are insulted by this fellow’s words.
