Don't need a reason

I think I've seen a sign,
But its a very fine line,
If you want it all,
An' don't lose track,
For on our back,
There's no weight of wings,
When they shine is hard to say,
But some things never fade away,
We only hurt the ones we love,
Why we don't need a reason,
We only give what we think we deserve,
An' that's something to believe in,
