Deceitfulness of Sin
Man makes the same mistakes over and over, even though history repeatedly warns him about the folly of his sins. Paul pinpointed the problem in Romans 1. He said that although man has a limited knowledge of God in creation, he chooses not to glorify Him, nor is he thankful. As a result, he becomes vain in his imaginations and his foolish heart is “darkened.” He no longer discerns right from wrong, but actually begins to think that right is wrong.
The deceitfulness of sin is vividly seen in the life of the French philosopher Rousseau. He declared, “No man can come to the throne of God and say, Im a better man than Rousseau.” When he knew death was close at hand, he boasted, “Ah, how happy a thing it is to die, when one has no reason for remorse or self-reproach.” Then he prayed, “Eternal Being, the soul that I am going to give Thee back is as pure at this moment as it was when it proceeded from Thee; render it a partaker of Thy felicity!”
This is an amazing statement when you realize that Rousseau didnt profess to be born again. In his writings he advocated adultery and suicide, and more that 20 years he lived in licentiousness. Most of his children were born out of wedlock and sent to a foundling home. He was mean, treacherous, hypocritical, and blasphemous.
