Imagine there's no Heaven,
It's easy if you try.
No Hell below us,
Above us only sky.
Imagine all the people, living life in peace.
You may say I'm a dreamer,
But I'm not the only one.
I hope someday you'll join us and the world can live as one,
Imagine no possessions,
It isn't hard to do.
Nothing to kill or die for,
And no religion too.

In spite of my Christian belief and this view/opinion of Lennon going against it...I can't help but think that the sentiment of togetherness and world peace is brilliant. The tune also sits the song.
Best wishes, GS
