In this fourth chapter of the Book of Jonah, (Jonah 4), the prophet Jonah has a strange reaction to his success. He's angry, and sulky. He thinks he knows better than God does. What is this story about?

Rev. George McCurdy, in his exegesis of this chapter, offers a summary in his Study Guide for the Book of Jonah, which is available for free as a .pdf, for your use. Below, we've excerpted part of his summary, and edited it for use in this context.

The people of the Jewish church in Jonah's time didn't want to reconsider their belief in their "most-favored-nation status." They challenged the Lord. They couldn't understand why He wanted to save their enemies in Nineveh.

Despite the hard lessons in chapters 1 and 2, and his success as described in chapter 3, Jonah still thought he knew better than the Lord. He thought that God was being too soft and loving -- too forgiving -- and that He needed to come around to Jonah’s tougher view.

Jonah got so angry and vengeful that he preferred to die rather than approve of the Lord’s way to save the Ninevites. His self-love wanted shade -- protection for its concepts. The Lord needed to bring such thinking to an end; the worm brought about death to the gourd from within. The Lord then sent a vehement east wind, that represents a blowing away of the stagnant thinking of the church.

The Lord's heavenly sun shone upon Jonah, but he felt faint. Here, Jonah's insistence on his own troubling view of things made him uncomfortable with the Lord’s view. The Divine guidance offered him a way to learn to enjoy the success of his neighbors as his own, but he wouldn't take it.

For us, then -- what? This story is telling us that we can't just keep the truths of the Word for ourselves; we have to go to Nineveh and share them. And then, if people start to hear them, and use them to turn their lives around, we can't allow ourselves to get resentful that the Lord accepts their repentance and forgives them. It's a very human reaction; think of the disciples vying to be first in the Lord's command structure (Luke 9:46), or the brother of the prodigal son (Luke 15:28-29), or the workers in the vineyard who had worked all day for a denarius (Matthew 20:10-12). But... it's not a good reaction. The Lord doesn't admire it in Jonah, and doesn't admire it when it crops up in our minds, either.

Rev. Martin Pennington recommends several explanatory passages from Swedenborg's theological writings:

"Shade or shadow means the perception of good and truth lies in obscurity." (Arcana Coelestia 2367)

"A vine is spiritual good (the spiritual church)". (Arcana Coelestia 217)

"A worm represents falsity gnawing away and tormenting one." (Arcana Coelestia 8481)

"'And the sun grew hot' in the contrary sense means self-love and love of the world." (Arcana Coelestia 8487)

And... here's a link to an interesting (audio) sermon on this chapter, by Rev. Todd Beiswenger.

5268. 'And the seven thin and bad cows coming up after them are seven years' means a state when falsity attacking the interior natural is multiplied. This is clear from the meaning of 'cows' in the genuine sense as truths within the interior natural, dealt with in 5198, 5265, but in the contrary sense as falsities there, dealt with in 5202, so that the former are called 'good cows', but the latter 'thin and bad'; from the meaning of 'coming up' as an advance made towards things that are interior, dealt with in 5202; and from the meaning of 'years' as states, dealt with just above in 5265. Even as 'seven' means that which is holy, so in the contrary sense it means that which is unholy. For most things in the Word have a contrary meaning as well, the reason for this being that when the selfsame things as come into being in heaven pass downwards in the direction of hell, they are converted into things of an opposite nature and become in actual fact their opposites. Consequently things that are holy, meant by 'seven', are made in that place into those that are unholy.

[2] Let references to the number seven found solely in the Book of Revelation serve to prove that 'seven' is used to mean both holy things and unholy ones. The following are places where holy things are meant,

John to the seven Churches: Grace and peace from Him who is and who was and who is to come, and from the seven spirits who are before His throne. Revelation 1:4.

These things says He who has the seven spirits and the seven stars. Revelation 3:1.

From the throne there were coming seven lamps of fire burning before the throne, which are the seven spirits of God. Revelation 4:5.

I saw on the right hand of Him sitting on the throne a book written within and on the back, sealed with seven seals. Revelation 5:1.

I looked, and behold, in the midst of the throne, a Lamb standing as though it had been slain, having seven horns and seven eyes, which are the seven spirits of God sent out into all the earth. Revelation 5:6.

To the seven angels were given seven trumpets. Revelation 8:1.

In the days of the voice of the seventh angel the mystery of God was to be fulfilled. Revelation 10:7.

Out of the temple came the seven angels having the seven plagues, clothed in linen, white and splendid, and girded around their breasts with golden girdles. Then one of the four living creatures gave to the seven angels seven golden bowls. Revelation 15:6-7.

[3] The fact that 'seven' in the contrary sense means things that are unholy is evident from the following places, also in the Book of Revelation,

Behold, a great fiery-red dragon having seven heads and ten horns, and on his heads seven jewels. Revelation 12:3.

I saw a beast coming up out of the sea, which had seven heads and ten horns, and on its horns ten jewels, but on its heads a blasphemous name. Revelation 13:1.

I saw a woman sitting on a scarlet beast, full of blasphemous names; and it had seven heads and ten horns. Here is the understanding of this - if anyone has the wisdom: The seven heads are seven mountains on which the woman is seated; and they are seven kings. The beast which was, and is not, he is the eighth king, and is of the seven, and is going away into perdition. Revelation 17:3, 7, 9-11.
