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.

2441. That 'the sun had gone forth over the earth' means the final period which is called the Last Judgement is clear from the meaning of 'sunrise' when the subject is the times and states of the Church. That the times of the day, like the seasons of the year also, in the internal sense mean the consecutive states of the Church has been shown already in 2323, and that 'the dawn' or 'the morning' means the coming of the Lord or approach of His kingdom, in 2405. Thus 'sunrise' or its going forth over the earth is His actual arrival or presence, the reason being that both the sun and the east where it rises mean the Lord - 'the sun', see 31, 32, 1053, 1521, 1529-1531, 2120, and 'the east', 101.

[2] The reason the Lord's arrival or presence coincides with the final period called the judgement is that His presence separates the good from the evil, and leads on to the good being raised into heaven and the evil casting themselves down into hell. For in the next life the Lord is the Sun of the whole of heaven, see 1053, 1521, 1529-1531. Actually it is the Divine celestial manifestation of His Love which appears before their very eyes as the sun and produces the light itself of heaven. To the extent therefore that those in the next life abide in celestial love they are raised up into that celestial light which comes from the Lord. But to the extent they are remote from celestial love they cast themselves away from that light into the darkness of hell.

[3] This then is the reason why 'sunrise' which means the Lord's arrival or presence entails both the salvation of the good and the condemnation of the evil; and why at this point it is first stated that 'Lot came to Zoar', that is, that people represented here by Lot were saved, and immediately after this that 'Jehovah rained on Sodom and Gomorrah brimstone and fire', that is, the evil were condemned.

[4] To those there who are immersed in the evils of self-love and love of the world, that is, who hate all things to do with love to the Lord and charity towards the neighbour, the light of heaven actually appears as thick darkness. This is why it is said in the Word that to those people the sun was darkened, which means that they rejected everything to do with love and charity and accepted everything contrary to these, as in Ezekiel,

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

Anyone may see that 'covering the heavens', 'darkening the stars', 'covering the sun', and 'making the bright lights dark' mean different things from these.

[5] Similarly in Isaiah,

The sun will be darkened in its going forth and the moon will not give its light. Isaiah 13:9-10.

And in Joel,

The sun and the moon are darkened, and the stars withdraw their shining. Joel 2:2, 10.

This therefore shows what is meant by these words spoken by the Lord when He was describing the final period of the Church which is called the judgement, in Matthew,

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. Matthew 24:29.

'The sun' is not used to mean the sun, nor 'the moon' the moon, nor 'stars' the stars, but 'the sun' is used to mean love and charity, 'the moon' faith derived from these, and 'the stars' cognitions of good and truth, which are said to have been darkened, to lose their light, and to fall from heaven when the acknowledgement of the Lord, and love to Him and charity towards the neighbour, cease to exist any longer. And when these have become non-existent self-love together with falsities deriving from it take possession of man; for the one thing results as a consequence of the other.

[6] This also explains the following in John,

The fourth angel poured out his bowl into the sun and it was allowed to scorch men with fire; therefore men were burned by the fierce heat, and they blasphemed the name of God. Revelation 16:8-9.

This too refers to the last times of the Church when all love and charity is being annihilated, or to express it in ordinary language, when no faith exists any longer. The annihilation of love and charity is meant by the statement that the bowl was poured out into the sun; consequently it is in that case self-love and its desires that are meant by the statement that men were scorched with fire and that they were burned by a fierce heat; and this led to their blaspheming the name of God.

[7] By 'the sun' the Ancient Church understood nothing other than the Lord and the Divine celestial manifestation of His love. It was their custom when praying therefore to turn towards the rising of the sun - yet without giving any thought at all to the sun itself. Later on however when their descendants had lost even this together with every other representative and meaningful sign they began to worship the sun and moon themselves. This kind of worship spread to very many nations, so much so that they dedicated temples to the sun and to the moon, and erected pillars. And because the sun and moon now assumed an opposite meaning they mean self-love and love of the world, which are the complete reverse of celestial and spiritual love.

[8] In the Word therefore worshipping the sun and moon is used to mean worship of self and of the world, as in Moses,

Lest you lift your eyes to heaven and you see the sun and moon and stars, all the host of heaven, and you are drawn away and bow down to them and serve them. Deuteronomy 4:19.

And in the same author,

If anyone has gone and served other gods, and bowed down to them, and to the sun or moon, or to all the host of heaven, which I have not commanded, you shall stone them with stones, and they shall die. Deuteronomy 17:3, 5.

People turned the worship of old into such idolatry when they no longer believed that anything internal was meant in the religious observances of the Church, only that which is external.

[9] Similarly in Jeremiah,

At that time the bones of the kings of Judah, of the princes, of the priests, of the prophets, and of the inhabitants of Jerusalem, they will spread before the sun and the moon and all the host of heaven which they have loved and which they have served. Jeremiah 8:1-2.

'The sun' stands for self-love and its desires. 'Spreading out the bones' means the hellish things which such people possess. In the same prophet,

He will break down the pillars of the house of the sun that is in the land of Egypt, and the houses of the gods of Egypt he will burn with fire. Jeremiah 43:13.

'The pillars of the house of the sun' stands for worship of self.
