As I usually find with most of LIGHTS' songs, there are two ways to look at the person she's talking about.
In this case, this person is her life, her hope, her road, her way, her light. This could either be a human being, like a boyfriend, a parent, etc... Or it could be God, which is the Christian way to look at it. So I think that depending on who you are, you can interpret it to whatever you like. You can fit it to what's going on in your life at the moment.
