In the Christian Bible it is written: "For God so loved the world, that He gave His only begotten Son, that whoever believes in Him should not perish, but have eternal life. (John 3:16)
But what is this 'eternal life'? And why is it that there are so many differing answers to this question within the various sects and branches that make up Christianity?
One thing that most seem to agree is that the physical constraints, pain and suffering of this World are absent. But happiness requires sadness to it to be experienced, joy requires sorrow, lack of pain requires pain. Take away one side of these equations and one is not left with something wonderful. One is left with nothing. If there is no contrast then there is no way to comprehend one's existence, at least not to a mind that bears sufficient resemblance to my current mind to be called me. I cannot both be an individual and lack the constraints that this world includes.
I'm still puzzled.
