God, Love, and Reality

‘God is Love’ is an accepted saying in almost all religions, isn’t it so? Should we not probe this statement?
What is meant here is devotional Love, of course. I personally notice within myself that Love, just like Compassion, Romantic love, Fear, Hatred, wonder and anger, is an emotion. True, it is the only emotion that unites instead of separates. Just because a feeling of oneness with the object of emotion is felt in devotional love, can we rule it out of the group of emotions and call it God? Is it not still an emotion that comes and goes? It is never permanent.
Perhaps it is because a deep feeling of oneness along with ecstasy is felt in devotional love that it turned out to be a good metaphor for God. God or the Ultimate Reality is naturally the original cause for the feeling of devotional love, just as it is the source for everything else also. Love with its euphoria and ecstasy is felt and misunderstood to be a substitute for the Ultimate itself.
Yet, this misunderstanding has some meaning when we consider that our awareness has always something or other attached to it, a thought, a mood, an image, a feeling or an emotion. Awareness is never alone in its pure form. In my case when the mind is bereft of any thought or image, it is a lurking fear that gets attached to awareness. And fear is one of the most disturbing of the emotions. For some others it may be resentment, anger or some other separating emotion. If instead of fear or anger, if the most desirable, ecstatic Love were to attach itself to my awareness there would be nothing more to desire for. Love being a unifying emotion, when it is attached to awareness in its pure form along with its euphoria and ecstasy, we can perhaps really call it God or the Ultimate Reality without touching upon the question of omnipotence.. There will then be a Oneness, a Unity of the whole, awareness, love, the universe as the object of love, the ecstasy and everything else combined into one complete entity!
The problem is only that Love has to rise itself from within, and cannot be forcibly brought in. I now realize the utter need for devotional Love.
