Lyric discussion by mmm10 

The song isn't about a blowjob or worshipping the devil!

If you look at the lyrics of the song, other songs in the album, and even parts of the music video, the answer seems clear to me - Madonna is questioning her faith as a Catholic/Christian, and is looking to god (the power itself, not of a religion) for an answer. There is so much hypocrasy in religion that she's found it hard to believe everything that she was taught to believe from the bible. This also explains why there's a burning of a cross in the music video. The controversy of it is an added bonus for her as well. Finally, not long after Like a Prayer, Madonna started getting interested and involved with Kabbalah. Therefore, the song is about religion, NOT a sexual experience.
