Unless You are Born Again
Genesis 6:5, ‘The Lord saw how great man's wickedness on the earth had become, and that every inclination of the thoughts of his heart was only evil all the time. After the fall of Adam (not from grace as is usually put) in the Garden of Eden when He rebelled against a life of obedience to God, his nature became sinful (rebellious, disobedience, selfish). It did not take long before the evil became prevalent in the world. Now sin is just a manifestation of the sinfulness of our nature but it is our nature that is sinful. For example, when is a tree a mango tree, is it when it produces fruit that it is called a mango tree or is it even before it produces fruit. Of course the tree is a mango tree even before it produces the mango fruit. The fruit is just the manifestation of the nature of the tree and so it is with the nature of man, you are sinful not because you sin but because that is your nature. Now the nature of man is not gained from the world after birth by exposure to sin
