I was thrilled to find this book yesterday!!
"I am convinced that the way we image—and gender—God affects the way we value gender among humans. A God who is always portrayed as male does harm girls (and women!) by suggesting that the most holy and whole “Person” is male. It absolutely gives femaleness a second-class value. I wanted my daughter to know in her imagination, which is where our deepest truths reside, that she, too, was fully in the “image of God.” And, because Susanna’s childhood joy was art projects, I wanted her to know that the exuberant joy she felt while creating art was one moment in which she knew God’s own exuberant joy."
