Tatyana Bistrevsky grew up as a Christian in a country that made an official point of denying God's existence. She'd go to school in her native USSR and present her homework assignment at the board in front of the class. All the T's would be crossed and I's dotted, she said, and the teacher would look at her and say: "Good, you did everything correctly. Now tell me what you did last night? Did you pray again last night? You prayed again last night – so you get a C. Now go sit down."
