When it comes to human nature, the Scriptures are blunt. No gilding of lilies here. Jeremiah says,
The heart is deceitful above all things,At root, humanity is so bad, the deceit so deep rooted, that the truth within a man's heart cannot be discovered, let alone mined. The intentions, the motivations, the principles, the emotions at play are all so complex and interwoven and confused that man is beyond understanding.
and desperately sick;
who can understand it?
“I the Lord search the heart
and test the mind,
to give every man according to his ways,
according to the fruit of his deeds.”
[Jeremiah 17:9-10]
Thus runs the Bible's indictment of us all.
Not so, says the modern politician. Humans are basically honest and decent folk. Oh, well, that settles that, then.
Whilst this optimistic view of mankind is everywhere, nowhere is it more dangerous than in the corridors and offices of political power. It leads politicians to ignore the goals and motivations of human behaviour; instead, politicians they can benefit society hugely simply by passing rules (which all citizens will hasten to obey and comply with because they are honest and decent folk.) The passing of the law is all the that is required for a righteous outcome.
Recently this has been grandly displayed in New Zealand with the left-wing Labour Party gaining power.
