The heart is deceitful above all things, and desperately wicked: who can know it?
Jeremiah 17:11
"The infidel Hume once said that if there were anything in the forty-seventh proposition of Euclid that crossed any person’s selfish interest, or limited the power of any man or class of men, there would be hundreds who would dispute the mathematical demonstration that the square of thehypotenuse of a right-angled triangle is equal to the sum of the squares of the other two sides.
And so it is.
It is not difficult, with the mass of mankind, to gain their assent to the most absurd theories, if their passions or business interests lead the way; but it requires more than mere human reason to thoroughly convince a man of the plainest truth, against his inclinations.
Only the grace of God can subdue the evil heart of unbelief."
E.J. Waggoner
