You know it's a sin to tell a lie
Still, you keep saying "I love you"
It may be true, I wish I knew
But I'm giving fair warning to you

Be sure it's true when you say "I love you"
It's a sin to tell a lie
Millions of hearts have been broken
Just because these words were spoken

I love you, yes, I do, I love you
If you break my heart, I'll die
So be sure it's true when you say "I love you"
It's a sin to tell a lie

Be sure it's true when you say "I love you"
It's a sin to tell a lie
Millions of hearts have been broken
Just because these words are spoken

I love you, yes, I do, I love you
If you break my heart, I'll die
So be sure it's true when you say "I love you"
It's a sin to tell a lie
