"That Old-Time Religion" by Alixtii

Amy Madison wasn't really the prayerful type; she had never been religious. She had gotten into Wicca for the power, the ability to manipulate the universe, not for the spirituality. Her encounters with the UC Sunnydale Wicca group, who focused almost solely on the spirituality and had very little idea what a spell even was, did not do much to change that. She had paid lip service to their Belthane Bake Sale plans, and had begun to corrupt them slowly and surely as she showed them the darker side of their religion.
So she didn't really know why she made a prayer to Hecate every night before she went to bed. She didn't believe in the gods and goddesses, not literally as entities which lived in the sky somewhere. They were just names to invoke, more the means to the completion of spells which would grant her the ends that she desired. Nothing more.
Still, every night as she approached her bed, she'd pause and bring herself to the bosom of the Mother Goddess. It'd be a simple prayer, something along the lines of "Mother Hecate, look after me and help me get that new car I want." But it'd be a prayer, a single moment she would spend with her Goddess, part of something bigger than herself.
And one night, the Goddess spoke back.
