Purpose right here

How can I make my words 
As sweet as candy
And how can they reach your heart
For any holes you have inside it
Will be filled up by my love
Any lies someone whispers at night
Will perish with a promise 
I made with my mouth
''To forever have, to forever hold
To forever serve until we're old
To forever laugh, to forever cherish
To be grateful, to be merry
To be humble and not fear
To find purpose right here.''
