C. A. Blomquist’s journey into the Jewish faith began as a Lutheran child. She could not have known it then. As an adult who has embraced Judaism, she has this to say:
[T]his year I’m going to spend some time with the book that laid the groundwork for my Jewish life— my faded, tattered copy of Egermeier’s Bible Story Book. Although the publishers likely never intended it, the book has become my own profoundly Jewish text, perfect for Shavuot study and reflection. When I read it, I will relive my first experience of Jewish study. I will picture my small blonde head bent over the text, absorbing a lifetime’s worth of lessons from the stories of my people.
One more cite. It helps explain why the Old Testament speaks to people, and always will, in ways that others may never understand:
[T]hen there was David, my girlhood crush: David the shepherd boy, David the strong and savvy warrior, David the builder, David the flawed but righteous king. No teeny-bopper idol in Tiger Beat magazine could compete. Most of all, I loved David the poet. A weakness of Egermeier’s was that it did not contain my very favorite part of the Bible: the Psalms. So, I kept my RSV Bible at hand to consult after reading about David and gazing at the illustrations of him in Egermeier’s.
Read the whole thing. There are Jews who feel threatened by the fact that some Jews are becoming messianic (Christian) Jews (and have the gall to continue to keep a kosher table, or keep one for the first time). There are Christians who feel threatened by the fact that some Christians are becoming Jews. Caution is in order, and if we are friends with the people in question, and we ourselves have strong religious convictions, we might pass on very strong words of warning.
On the other hand, given the fact that people prefer the devil they don't know to the one they already know (I'm trying to be even-handed here, and bracket out the question of God's leading), conversions in all directions are to be expected.
