If the most important commandment is to Love God with all our hearts, souls, minds, and strengths is applicable, it would appear that God craves our attention. This, however, would make no logical sense if God is by definition complete, needing nothing. Why would God command us to love Him?
God doesn't have to NEED to be loved in order to desire it. He loves and desires love from abundance and generosity, not need. And considering the great pleasure we get from loving Him, it can hardly be called a selfish desire.
