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.

1808. 'And count the stars' means a representation of goods and truths in a mental view of the constellations. This is clear from what has just been stated, and also from the representation and meaning of 'the stars' as goods and truths. Stars are mentioned many times in the Word, and in every instance they mean goods and truths, and also in the contrary sense evils and falsities. Or what amounts to the same, they mean angels or communities of angels, and also in the contrary sense evil spirits and groupings of these. When angels or communities of angels are meant they are stars that are motionless, but when evil spirits and groupings of these are meant, they are stars that wander, as I have seen on many occasions.

[2] The fact that everything in the sky above and on the earth beneath is representative of celestial and spiritual things has become clear from the plain evidence that things similar to those that appear before the eyes in the sky and on the earth are also manifested visually in the world of spirits, and this as clearly as in broad daylight. There they are nothing other than representatives. For example, when a starry sky appears and the stars in it are motionless one knows instantly that they mean goods and truths; and when the stars appear wandering one knows instantly that they mean evils and falsities. And from the way in which the stars shine and sparkle the nature of them is made clear too, besides countless other considerations. Consequently if anyone is willing to be wise in his thinking he may know where all things on earth originate, namely in the Lord. And the reason why these things do not present themselves on earth in non-physical ideas but in actual physical objects is that all things, both celestial and spiritual, which derive from the Lord are living and essential, or substantial (as they are called), and therefore manifest themselves as actual objects within the natural order, see 1632.

[3] That 'the stars' represents and means goods and truths becomes clear from the following places in the Word: In Isaiah,

The stars of the heavens and their constellations do not give their light. The sun is darkened in its going forth, and the moon does not shed its light And I will punish the world for evil, and the wicked for their iniquity. Isaiah 13:10-11.

The subject here is the day of a visiting with punishment. Anyone may see that here 'the stars' and 'the constellations' are not used to mean stars and constellations but truths and goods, 'the sun' to mean love, and 'the moon' to mean faith; for falsities and evils which 'darken' are being referred to.

[4] In Ezekiel,

When I have blotted you out I will cover the heavens; I will darken their stars. I will cover the sun with a cloud, and the moon will not give its light. All the bright lights I will make dark over you, and I will put darkness over your land. Ezekiel 32:7-8.

Here the meaning is similar. In Joel,

The earth quaked before Him, the heavens trembled. The sun and the moon were darkened, and the stars withdrew their shining. Joel 2:10; 3:15.

Here the meaning is similar. In David,

Praise Jehovah, sun and moon, praise Him, all stars of light! Praise Him, heavens of heavens! Psalms 148:3-4.

Here the meaning is similar.

[5] That 'stars' does not mean stars but goods and truths, or what amounts to the same, people who are wholly taken up with goods and truths, as angels are, is stated plainly in John,

I saw the Son of Man holding in His right hand seven stars. As for the mystery of the seven stars which you saw in My right hand, and the seven lampstands, the seven stars are the angels of the seven Churches; while the seven lampstands which you saw are the seven Churches. Revelation 1:16, 20.

[6] In the same book,

The fourth angel sounded, and a third part of the sun was struck, and a third part of the moon, and a third part of the stars, so that a third part of them was darkened, and the day did not shine for a third part of it, and the night likewise. Revelation 8:12.

Here it is quite clear that good and truth were darkened. In Daniel,

There came forth a little horn, and it grew very much towards the south, and towards the east, and towards the glorious [land]. And it grew even towards the host of heaven, and cast down to earth some of the host, and of the stars, and trampled on them. Daniel 8:9-10.

Clearly 'the host of heaven' and 'the stars' are goods and truths, which were 'trampled on'.

[7] These places also show what is meant by the Lord's words in Matthew,

At the close of the age, immediately after the affliction of those days, the sun will be darkened, and the moon will not give its light, and the stars will fall from heaven, and the powers of the heavens will be shaken. Matthew 24:29.

And in Luke,

There will be signs in sun and moon and stars, and upon the earth distress of nations in despair, at the roaring of the sea and of the ocean. Luke 21:25.

Here 'the sun' does not at all mean the sun, nor 'the moon' the moon, nor 'stars' the stars, nor 'sea' the sea, but the things which these represent; that is to say, 'the sun' means the celestial things of love, 'moon' the spiritual things, 'stars' goods and truths, or cognitions of good and truth, which around the close of the age when no faith, that is, no charity, exists, are thus darkened.
