I have two favorite Scriptural sarcasms which I find to be sheer genius. One in the Old Testament, and one in the New. The first is from I Kings 18:21-39. Elijah told the people that they should choose two bullocks and place them on two altars of wood. He then said:
"And call ye on the name of your gods, and I will call on the name of the Lord: and the God that answers by fire, let him be God"
They all agreed, and so the priests of Baal went first:
"And they took the bullock which was given them, and they dressed it, and called on the name of Baal from morning even until noon, saying, O BAAL, hear us. But there was no voice, nor any that answered. And they LEAPED upon the altar which was made.
And it came to pass at noon, that Elijah mocked them, and said, Cry aloud: for he is a god; either he is talking, or he is pursuing, or he is on a journey, or peradventure he sleeps, and must be wakened.
Better though, when this verse is read from The Living Bible:
"About noontime, Elijah began mocking them. ‘You’ll have to shout louder than that,’ he scoffed, ‘to catch the attention of your god! Perhaps he is talking to someone, or is out sitting on the toilet, or maybe he is away on a trip, or is asleep and needs to be wakened.’"
The best though, is Matt 21:24-27. The proverb tells us to "Answer a fool according to a fool." And Jesus was a Master at doing this. The Chief Priest and Elders of the temple asked Jesus by what authority He did the things He did. Here then is my favorite New Testament sarcasm by Jesus:
"And Jesus answered and said unto them, I also will ask you one thing, which IF you tell me, I in like wise will tell you by what authority I do these things. The baptism of John, whence was it? From heaven, or of men? And they reasoned with themselves, saying, If we shall say, From heaven; He will say unto us, Why did you not then believe him? But if we shall say, Of men; we fear the people; for all hold John as a prophet. And they answered Jesus, and said, we cannot tell.
And He [Jesus] said unto them, NEITHER TELL I YOU by what authority I do these things"
Sarcasm? Maybe, but pure genius...
