Charles H. Spurgeon on Psalms 10:6

The testimony of the sixth verse concludes the evidence against the prisoner upon the first charge of pride, and certainly it is conclusive in the highest degree. The present witness has been prying into the secret chambers of the heart, and has come to tell us what he has heard. "He hath said in his heart, I shall not be moved: for I shall never be in adversity." O impertinence runs to seed! The man thinks himself immutable, and omnipotent too, for he, he is never to be in adversity. He counts himself a privileged man. He sits alone, and shall see no sorrow. His nest is in the stars, and he dreams not of a hand that shall pluck him thence. But let us remember that this man's house is built upon the sand, upon a foundation no more substantial than the rolling waves of the sea. He that is too secure is never safe. Boastings are not buttresses, and self-confidence is a sorry bulwark. This is the ruin of fools, that when they succeed they become too big, and swell with self-conceit, as if their summer would last for ever, and their flowers bloom on eternally. Be humble, O man! for thou art mortal, and thy lot is mutable.

The second crime is now to be proved. The fact that the man is proud and arrogant may go a long way to prove that he is vindicative and cruel. Haman's pride was the father of a cruel design to murder all the Jews. Nebuchadnezzar builds an idol; in pride he commands all men to bow before it; and then cruelly stands ready to heat the furnace seven times hotter for those who will not yield to his imperious will. Every proud thought is twin brother to a cruel thought. He who exalts himself will despise others, and one step further will make him a tyrant.
