This song is about how so many people are aware of issues that are happening (such as poverty in Northern Africa) but still don't do anything about it, because it doesn't affect them. That's why somebody needs to make a move, because we all know what's going.
I think yhere are two possible meanings for this song. The first is that the singer has been unfaithful to God, and he's wondering how God still love him. The second is that the singer is asking somebody he left or hurt if and how they still love him.
