Love?

My heart is fastly beating
Caused by this strange feeling
Is this what they say a gift from above
The precious thing they call love?

It's a heaven's blessing
This is what some people saying
While some do not agree
'Cause only hurt is what they always see.

Which of the two I will agree with?
If this is the first time i feel it
Will I believe that love keeps you smiling
Or only sorrow it always bring?
