Where has all the passion and fire gone?

I think that God has been teaching me allot in the past couple of years, but I have to wonder where has it all gone?
There was a time when I was really in Love with my god. These days I feel like a fake everytime I say the words out loud. How can I say that I love Him when I don't act like I do? How do I act like I do? In the past couple of years I have found allot of freedom in god, I have learned that its OK to be me, no matter how screwed up I am. but in my freedom have I lost how to be in love with the only thing that really matters in my life? How do you love someone, how do you show that person that you love him?

I want to be in Love.
