Glynn Cardy has been posting a serious of answers in his blog to theological questions that were posed to him by a five year old girl. His latest posting answers the question "Why is God called God, if God is love?"
The answer that he gave was as follows:
I love your questions!
Words called nouns name an object that we can see – like t-r-e-e names that thing with leaves and branches outside my window. The word G-o-d though names something we can’t see. It names a spiritual power that flows through people’s lives. That power is within, beyond, and between us. It is something we experience, like feelings, but can’t be proved scientifically.
Christians believe that the main feeling and evidence of that spiritual power is love. Sometimes we might meet a person who is so full of goodness that it seems that while she or he is with us that spiritual power called God is with us. This was the experience of people who knew Jesus. He was stuffed full of God.
Some people want to call that spiritual power a ‘Him’ or a ‘Lord’. They make G-o-d into a noun. I prefer to think of G-o-d as a verb: a flowing, moving, loving force. Sort of like the power that lights up the bulb rather than the light bulb itself.
