Tear it All Down

I am about to leave for another year at school. My life is moving forward, I am changing. I come home to my house that I grew up in, and recognize it for only that. It is not my home now. My new home is wherever I lay my head down to sleep, wherever my closest friends are, wherever God takes me. 
This song talks about the past, anything and everything that they have experienced and how it has changed them. 
I guess my life growing up would then be this house that I am tearing down. Leaving it all behind, looking ahead.
