Are You a "Pregnant" Christian?

When a woman conceives, she is called pregnant. She is with-child and expectantly awaiting the arrival of her baby. While the labor is hard, she would not put it off. Her joy and expectation outweigh the pain she will feel. And while she may be afraid of the weighty task of raising a child before her, to delay the inevitable is unthinkable, let alone impossible. So what does this have to do with Christianity and faith? How are Christians pregnant?
