Without suffering there would be no free will. Without free will the whole human purpose would loose meaning. God doesn't care about good and evil. Only cares about how do we respond to life from the standpoint of absolute freedom. Are we gonna suffer from the evil, are we gonna reject everything that doesn't suit our view of what reality should or shouldn't be, and live in distrust of life and loosing the connexion with the exterior world ? Are we gonna trust our intuition and guide ourselves through love in life to withstand every thing that arises from without, and grow and evolve in mind body and heart from within using the events in our life as steps down the ladder of our core ?
