She's Jewish. Her view of the afterlife is different from Christian views.
May be. But God’s view is what counts
And He has no distinction between Jews or Gentiles, man or woman, slave or free in this dispensation of the GRACE of God. She can think of do anything she wants, but she still has a day appointed to stand before Him with His Reconciliation Book open. The FINISHED WORK OF CHRIST is the ONLY way to be included in that book. Of life.
It doesn't matter what her view of the afterlife is. What matters is God's view.
ALL are called to repent and accept Jesus Christ as their Lord and Savior. Those who reject Him will not enter the Kingdom of Heaven.
