I see that in the intorduction to Tobit that the OSB has a cross reference to John 3:16. Is this correct?
The Book of Tobit is a love story. A father sends his only son into the world so that he may find a bride, save her, and bring her back rejoicing to his parents.
A comparison with John 3:16 could read
A father
For God sends his only son into the world
so loved the world, that he gave his only begotten Son, so that he may find a bride,
that whosoever believeth in him save her,
should not perish,and bring her back rejoicing to his parents.
but have everlasting life.
