They know that God loves all and desires none to perish. So He "abandons" them to their own will, 'left in the hands of their own counsel' as it were. This life isn't a free ride to heaven for some and to hell for the rest; it's a journey with a test, of how we will comport ourselves when the Master is effectively gone away.
The most critical lesson to be learned, and the heart of the New Covenant, is that man needs God; man needs grace to put it another way. "Apart from Me you can do nothing." Adam, and his fallen descendants, thought/think otherwise until they finally learn of that need by experiencing their deprivation and so overcoming the pride and ignorance that separates us from Him. So that they might will rightly when revelation and grace are offered. Obedience can only be based on that relationship, not on man's own efforts as if he possessed any righteousness apart from God. Only God can place His law in man's mind and write it on his heart. And that relationship is entered into and established by faith.
