Won't do it justice, but there was a sermon I thought was pretty interesting a couple years ago relating to the passage where Jesus asks Peter if he loves him.
Basically Jesus asks Peter three times whether Peter loves him. And three times Peter says "You know I love you".
Seems like a pretty uneventful passage in English.
Our pastor elaborated a bit and explained that in the original (greek / aramaic, don't remember which), there are several kinds of love.
What Jesus is saying is basically "Do you love me perfectly, the way only God can?"
What Peter is replying is basically "I love you the way that man can, imperfectly."
This happens twice.
The third time Jesus asks "Do you love me imperfectly, the way that a man can?" And Peter gives the same refrain.
Put's a different spin on it since in the first it's just a repetitive exchange, but in the second form it's an instance of God coming down to man's level.
Thought that seemed really interesting.
