What did Jesus believe about the story of Jonah? His sentiments in this regard were emphatically stated.
Then certain of the scribes and Pharisees answered him, saying, Teacher, we would see a sign from thee. But he answered and said unto them, An evil and adulterous generation seeketh after a sign; and there shall no sign be given it but the sign of Jonah the prophet: for as Jonah was three days and three nights in the belly of the whale; so shall the Son of man be three days and three nights in the heart of the earth. The men of Nineveh shall stand up in the judgment with this generation, and shall condemn it: for they repented at the preaching of Jonah; and behold, a greater than Jonah is here (Matthew 12:38-41).
Quite clearly, Jesus accepted the story of Jonah as an accurate description of a real, historical event. He included not only the fact that Jonah spent three days in the belly of the fish, but also affirmed that the city of Nineveh repented at the preaching of Jonah. If the story of Jonah were simply an allegory or myth, Jesus’ entire point about being in the belly of the Earth for as long as Jonah was in the belly of the fish would be weakened to the point of ridiculousness. For, if Jonah wasn’t ever really in the belly of the fish, then what would that say about the Son of Man actually being in the belly of the Earth?
See what happens when we question whether or not God means what he says and says what he means? We always turn him into a liar and his "lies" lead to other "lies" of God.
Accepting the testimony of Jesus Christ further demands that the global Flood of Noah be taken as a literal, historic event. The Lord Himself addressed the topic of the great Flood in Luke 17:26-30 (cf. Matthew 24:39) when He drew the following parallel:
And as it came to pass in the days of Noah, even so shall it be also in the days of the Son of man. They ate, they drank, they married, they were given in marriage, until the day that Noah entered into the ark, and the flood came, and destroyed them all. Likewise even as it came to pass in the days of Lot; they ate, they drank, they bought, they sold, they planted, they builded; but in the day that Lot went out from Sodom it rained fire and brimstone from heaven, and destroyed them all: after the same manner shall it be in the day that the Son of man is revealed (emp. added).
The Lord depicted an impending doom that was to befall the Jews of His day who would not heed the Word of God. For the purpose of this article, however, note the context in which Jesus discussed the Flood destruction of Genesis 6-8. He placed the Flood alongside the destruction of Sodom, and He also placed it alongside the destruction of the ungodly at His Second Coming. John Whitcomb correctly noted that the word “all” must refer to the totality of people on the entire Earth in Noah’s day, and in Sodom during Lot’s time. Jesus’ argument would be weakened considerably if some of the people on the Earth, besides Noah’s family, escaped the Flood, or if certain Sodomites survived the fiery destruction sent from Heaven (1973, pp. 21-22). It is evident from the text that Jesus affirmed that the same number of ungodly sinners who escaped the Flood will be the same number of disobedient people who escape destruction at His Second Coming—none. From His remarks, one can clearly see that Jesus accepted the Genesis account of a global flood as a historical fact.
The sayings of Jesus contain numerous references to some of the Old Testament’s most extraordinary events. A person cannot consistently maintain a belief in Jesus and His teachings, while denying the details of the accounts that He endorsed as factual. The testimony of Jesus and the factual accuracy of the stories He commended stand together.
Let God be found true though every man a liar. Go ahead and believe what you want to about Jesus, BTS. I've had it with people's interpretations.
