Christianity ???

I am interested in talking about the religious scenes in Americanah. I am intrigued by Ifemelu's mother's spiritual experiences, but don't really know what to make of them. This is my second time reading Americanah, and while I definitely picked up on the ways that religion provided Adichi interesting ways of portraying the family dynamic. Such as using praying as a tool to speak to the father's progression of loosing faith in himself, or just general discrepancies between  the members of the family. But I'm interested in taking a more spiritual approach, and thinking more about the mother's relationship with God, and how and why her feelings towards God changes.
