God loves us infinitely more than our parents, and more than we can ever dream. Without that spirit of love, we would not see tomorrow. He constantly cleanses and replenishes us every night, and so we wake anew, ready to start another changed and changing dawn.
God also needs us. He wishes that we serve and assist Him in manifesting or unfolding His numerous dreams. We are His branches, and yet again in mystical parlance, we are like the Lover and the Beloved.
Sure, the Supreme is omnipotent, omniscient and omnipresent, but when through His Grace, one becomes a willing instrument to serve, then perhaps the word 'Master' invariably becomes too harsh.
