One who chants the holy name of the Lord is immediately freed from the reactions of unlimited sins, even if he chants indirectly [to indicate something else], jokingly, for musical entertainment, or even neglectfully. This is accepted by all the learned scholars of the scriptures.
Srimad Bhagavatam 6.2.14,
The human body is rarely achieved and although temporary like other bodies, it is meaningful because in human life one can perform devotional service. Even a slight amount of sincere devotional service can give one complete perfection.
Bharata Maharaja, Who had attained loving affection for the Supreme Lord, fell down from his position due to his affection of deer. Consequently, he had to accept the body of a deer in his next life. Unless we increase our faith in the Supreme Lord, we shall be attracted to many other things. That is the cause of our material bondage.
If one denies the state law, he will be put into prison and duly punished. Similarly, one may foolishly decry the existence of God, but ultimately one is responsible for his actions.
