"God" is a very complex idea deeply misunderstood even by the best minds we have around. God symbolizes UNITY in Reality through Rationality.(from Ratio, not appealing to thought, just mathematical Rationality) In turn, Rationality implies and requires interaction, interdependence, relationship, which can loosely be equated with connection or "Love". Hence why "God" is "Love". The most abstract form of it.
Needless to say, the simple-minded version of "God" is outrageously childish.
