Sree Sree Guru Gaurangau Jayatah!
The Supreme Lord does not interfere in the relative independence of the conditioned souls. The real self is atma, who thinks, feels and wills. Nobody on earth considers a dead body to be a person. As long as consciousness exists in it, it is considered a person. If the Supreme Lord exerts His power to make the conditioned souls forcibly inclined to Him, then the real self will be reduced to an inert thing. For that reason, the Supreme Lord resides in the heart of the conditioned soul as the indwelling monitor, Paramatma, appears in this world in different Transcendental Divine Forms and, sends His own personal associates in this world to persuade the conditioned souls so that they can willingly submit to Him.
You should go through the biography of the great devotee saint Prahlad Maharaj. He tried his best to change the mind of his son Virochan to worship the Supreme Lord, but in spite of his best efforts he failed and his son became a demon. But Prahlad Maharaj did not become unbalanced, thinking that due to Virochan's previous bad impressions imbibed by previous bad deeds, he could not accept his teachings. Prahlad Maharaj thought he had done his duty for the eternal welfare of the son but the son could not accept it due to his previous bad impressions.
Since the Supreme Lord and His powerful personal associates do not perform the pastimes of using force to change the mind of the worldly people, how can we do it? It is our duty to help the enslaved jivas by our ideal character to change their minds so that they can submit to the Supreme Lord and worship Him. But we should not make a firm determination to execute it because in case our desire is not fulfilled, we may become unstable.
