Could have Ignoring the parts you didn't like been where faith/belief was lost?
When I was young I had an amazing experience of God, and came away from it not with the conviction "God loves me" (although He certainly does) but with the conviction "God loves all of us." It's just who He is.
What I could not understand is how the authors of the Old Testament could portray God as they did. After years, decades of study I realized they saw God just as I had. However, the change from Hebrew to English and from ancient Eastern culture to modern Western culture was the issue. Along the way I came across rabbis, time and again, saying scripture was not meant to be read, it was intended to be studied. For how long? Decades wasn't nearly long enough. It takes a lifetime.
People are not choosing and passing over. That's being mistaken for where people are in their studies.
