This quote comes from a movie that you may or may not have scene. It's been awhile since it was out, but if you get the chance to see it I would recommend it.
If you don't take it too seriously.
Michael is a movie starring John Travolta. He plays the angel Michael who has come to earth to fulfill a mission involving three employees of a tabloid magazine.
I told you not to take it so seriously.
He is not your typical angel. He drinks, smokes and likes to dance in bars, among other things. But he gets the job done one way or another.
The quote I have for you is so spot on that it doesn't even need much by way of connecting it to scripture.
Hanging out in the bar with his two tabloid buddies Michael utters this line:
"Remember what John and Paul said."
His friends respond with: "the apostles?"
Michael answers "No the Beetles, all you need is love."
See? I told you.
Here's the scripture anyway just to keep things in perspective.
1 Corinthians 13:13 (NASB) But now faith, hope, love, abide these three; but the greatest of these is love.
Love for others.
It's all we need.
