Decay began to set in man, he had died and began to die. This means that man's will is just as dead as the rest of him, making him unable to choose to obey God. He is dead in his trespasses, and dead men do not choose life. The Lord looks down from heaven upon the children of men, To see if there are any who understand, who seek God. Then may you also do good who are accustomed to do evil.
All creation suffers from man's fall.
Both thorns and thistles it shall bring forth for you, And you shall eat the herb of the field. The great mystery of God's love is not that some are left to perish, for all are deserving eternal punishment, but that any are saved at all. Who then can choose to be born again, this decision was too important to be left with men. To revolt against this truth, is to exalt man's reason above Scripture, therefore above God. It reverts back to the fallacy of the Great Chain of Being, making God accessible by human reason, independent from what God has said.
