Unlike parents, whose guidance can be flawed, God encompasses all wisdom, power and impartiality
The following verse will shed light on this, which is, “You alone are my mother; You alone are my father; You alone are my relative and You alone are my friend; You alone are my knowledge and You alone are my wealth; O Lord of all Lords, You alone are my everything.” In verse #7.19 of the Bhagavad-Geeta, Lord Krishna states, “After efforts of many births, a yogi in the end becomes wise, and he takes My shelter. A great soul, who considers Lord Vasudeva thus as everything is very rare.” The answer, therefore, is: that God is very much more than a mother or father can ever be.These entities, i.e., a mother or a father have severe limitations. Their knowledge is very limited. They don’t know the Big Picture.
Far from it, they may guide their children wrongly. On the other hand, God is omniscient. He knows past, present and future also. Lord Krishna informs us what He can do. “By being specially kind, I, situated within, destroy the darkness, born of ignorance, by the shining lamp of knowledge.” (10.11) Then, a parent has limited resources that he or she can give to his or her children, whereas God has all the opulence in full. Sanjaya of the Mahabharata fame informs, “Where there is yogeshwara Shri Krishna, and where there is a soul linked to Him, there will be opulences (‘soubhagya’), victory (success), wealth, and morality.” (18.78)A parent can help only in a limited way. Suppose his or her child is unwell. What can he or she do besides arranging medical facilities and taking care of the best way possible?
