Charles H. Spurgeon on Psalms 146:3

Put not your trust in princes, etc. Through some kind of weakness, the soul of man, whensoever it is in tribulation here, despairs of God, and chooseth to rely on man. Let it be said to one when set in some affliction, "There is a great man by whom thou mayest be set free"; he smiles, he rejoiceth, he is lifted up. But if it is said to him, "God frees you", he is chilled, so to speak, by despair. The aid of a mortal is promised, and thou rejoicest; the aid of the Immortal is promised, and art thou sad? It is promised thee that thou shalt be freed by one who needeth to be freed with thee, and you exult as at some great aid: thou art promised that great Liberator, who needeth none to free him, and you despair, as though it were but a fable. Woe to such thoughts: they wander far; truly there is sad and great death in them. —Augustine.
