For the record,I am vehemently against someone being forced by their inlaws to change their religion in order to marry their son.
You don’t belief in Christ our savior your whole life and next day you dont.
So you assume that because she married a man of the Jewish faith that she has no relationship with Christ?
You need to get out more
I have many friends who are Jews who do believe in and accept Christ as our Lord and Savior, not all that unusual
In the same vein I know those who profess as Christians but do not acknowledge his role as Lord and Savior
