“I have sinned this time: the LORD is righteous, and I and my people are wicked.” -Exodus 9:27

“Now,” says Pharaoh, whilst the thunder is rolling through the sky, while the lightning-flashes are setting the very ground on fire, and while the hail is descending in big lumps of ice, now, says he, “I have sinned.” He is but a type and specimen of multitudes of the same class. How many a hardened rebel on shipboard, when the timbers are strained and creaking, when the mast is broken, and the ship is drifting before the gale, when the hungry waves are opening their mouths to swallow the ship up alive and quick as those that go into the pit-how many a hardened sailor has then bowed his knee, with tears in his eyes, and cried, “I have sinned!” But of what avail and of what value was his confession? The repentance that was born in the storm died in the calm; that repentance of his that was begotten amidst the thunder and the lightning, ceased so soon as all was hushed in quiet, and the man who was a pious mariner when on board ship, became the most wicked and abominable of sailors when he placed his foot on terra firma….But alas, for such a repentance! When the sun again shines, and the black clouds are withdrawn, sin comes again upon the man, and he becomes worse than before…If I have such here this morning, let me solemnly say to them, “Sirs, you have forgotten the feelings you had in your hours of alarm; but, remember, God has not forgotten the vows you then made.” Sailor, you said if God would spare you to see the land again, you would be his servant; you are not so, you have lied against God, you have made Him a false promise, for you have never kept the vow which your lips did utter. Couldst thou lie to thy fellow-man, and yet go unreproved? And thinkest thou that thou wilt lie against God, and yet go unpunished?…It is of no use for you to say, “I have sinned,” merely under the influence of terror, and then to forget it afterwards.  ~ C.H. Spurgeon
