Daniel, apart from the good counsel given above – I have heard this from Jews before. Some of their loved ones are in hell now, and some living are en route to it. It is a mistake to speak to her as "a Christian", rather than simply bringing Moses and the prophets to her attention. The tack I would take in evangelizing her would be, "Are you not familiar with your Jewish faith, of which, anticipation of Messiah was core?"
A great wrong has been done the Jewish peoples by the renegade and unbelieving rabbinate, sealing them against the knowledge of their Messiah, consigning vast multitudes to eternal Gehenna. From,
A Poet Arises In Israel,
I say the rabbis have led my people
into the curses of Moses
these past twenty centuries,
for if we had pleased God
and were under His sure covenant blessings
and protection, how is it possible
we had been spewed from the land
to be slaughtered and despised
among the goyim two thousand years
and to end in the ovens of Hitler?
The truth is – and only can be! –
we have followed treasonous leaders
in betrayal of our King,
and have reaped their destruction.
O nation of fools, we,
to be blinded so long!
As the prophets foretold,
the Gentiles came to His light,
and we followed our teachers
into darkness
even unto this blood-filled day!
Cast off the pretenders
who have slain our millions
and return to the one Book we are the people of!
With regard to those Jews living who are dear to her, it may be, were she to come to faith in the Messiah and King of Israel, the LORD might in His mercy grant her to touch the hearts of some of her people. Otherwise they may perish, along with her, if she persists in unbelief. He is a merciful Saviour – she should seek his favor and forgiveness.
