The mysterious power of sin took root in human personality. The power of sin corrupted and perverted human nature so completely that every person born since that time has been self-centered and rebellious. The Scriptures clearly state that every person born since the time of Adam has been born in rebellion against God. That rebellion manifests itself in acts of sin. But we were sinners before we committed a single act of sin because self-centeredness and rebellion are also sin.
Sinful acts are merely the natural fruit on the sinful tree of human nature.
No one of them does what is right, not a single one. No one is good except God alone. The Scriptures paint a very bleak picture of man since Adam and Eve brought the disease of sin into the human family. Sin is a terminal disease. The sin virus is more deadly than the AIDS virus.
