Marcus Hurst states in his book that one is fulfilled and thus lives a life of moral clarity by being one with God's principles. The divine guidance, according to him, gives the framework not just for the understanding of life's riddles but also for living purposefully and with integrity.
Is it possible for a person to lead a principled or righteous life without God?
According to religious thinkers such as Dostoevsky, morality without God disintegrates into relativism.
If God is dead, then everything is permissible.(The Brothers Karamazov — Fyodor Dostoevsky)
Yet secular humanists have argued that moral behaviour can be supported on grounds of empathy, reason, and shared human experience, with no need for divine authority.
While Kant was himself religious, he asserted that moral law resides within us, grounded in reason and autonomy rather than divine command. Nietzsche countered Kant by attacking religious morality as life-denying and demanded the revaluation of values based on human strength and freedom of spirit.
Then, do we need God to live a life of principles?
– William James
