Unconditional love. Not many of us know what that truly means. We often 'love' others with conditions. We expect them to love us in return and often punish them when they don't. Unconditional love is loving someone without conditions, pre-conditions or obligations, and is not something that comes easily to us humans. Two great examples of unconditional love are GOD and dogs, and Wendy J Francisco has penned a lovely little song about just that. She explains here how she came up with the idea for the song. Someone apparently claimed it was blasphemy to compare God with a dog, but that's really not her point, as she explains and as I understood it.
I think it's just a wonderful example of how important it is to be forgiving and unconditional.
