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.

9807. 'And his sons' means Divine Truth emanating from Divine Good. This is clear from the meaning of 'sons' as truths, dealt with in 489, 491, 533, 1147, 2623, 2803, 2813, 3373, 3704, at this point Divine Truth emanating from the Lord's Divine Good, since they were Aaron's sons and Aaron as the high priest represented the Lord in respect of Divine Good, as shown immediately above. Truths are meant by 'sons' because everything in the internal sense of the Word is spiritual, and 'sons' in the spiritual sense are those who are born anew from the Lord, thus are in possession of truths springing from good, so that in the abstract sense - when the persons are not envisaged - 'sons' are the actual truths which spring from good. These truths therefore are what should be understood in the Word by 'the sons of God', 'the king's sons', and 'the sons of the kingdom'. They are also the sons of new birth or regeneration. Furthermore the truths and forms of good present with the person who has been regenerated or born anew from the Lord are exactly like families in wide and long lines of descent from the one same father. There are those which resemble sons and daughters, those which resemble grandsons and granddaughters, those which resemble sons-in-law and daughters-in-law, and so relationships belonging to many degrees, thus to many kinds. Truths and forms of good arranged like this are what sons, daughters, grandsons, granddaughters, sons-in-law, daughters-in-law, in short, relatives belonging to different degrees and therefore different kinds, denote in the spiritual sense. I have been shown by actual experience that spiritual generations follow one another in that kind of order. And at the same time I have been told that this being so the truths and forms of good with a person who has been regenerated follow in that kind of order, since the angelic communities in heaven are arranged in that way and the truths and forms of good present with a person correspond to those communities. Therefore also the person whose truths and forms of good possess that kind of correspondence is heaven in the smallest form it takes, 9279.

[2] Anyone who knows that truths are meant by 'sons' and forms of good by 'daughters' can see many arcana in the Word, especially the prophetical part, which would otherwise lie hidden from view. For example he can see what is meant specifically by the Son of Man, which the Lord often calls Himself in the Word, namely Divine Truth emanating from His Divine Human, as is clear from the places where that title appears. Let these be quoted, in order that at the same time it may be established that 'the Son' means truth, as in John,

The crowd said to Jesus, Why do you say, The Son of Man must be lifted up? Who is this Son of Man? Jesus answered them, The light is with you for a brief while longer. Walk, as long as you have the light, lest the darkness overtakes you. As long as you have the light believe in the light, that you may be sons of the light. John 12:34-36.

From these words it is evident that 'the Son of Man' has the same meaning as 'the light'; for when the crowd asked, 'Who is this Son of Man?' the Lord answered that He was 'the light' in which they should believe. 'The light' means Divine Truth, see the places referred to in 9548, 9684, and so therefore does 'the Son of Man'.

[3] In Luke,

Blessed are you when people will hate you on account of the Son of Man. Luke 6:22.

'On account of the Son of Man' is on account of Divine Truth, which emanates from the Lord. Divine Truth constitutes the all of faith in and love to the Lord; and 'being hated' on account of these is blessedness. In the same gospel,

The days will come when you will desire to see one of the days of the Son of Man, but you will not see. Then they will say to you, Behold here! or Behold there! Do not go away or go in search. Luke 17:22-23.

'Desiring to see one of the days of the Son of Man' means desiring to see one of the states of truth that is authentically God's. The subject here is the end of the Church, when no faith exists any longer because there is no charity, at which time every truth that is genuinely God's is going to perish. And since God's truth is meant by 'the Son of Man' it says, 'Then they will say, Behold here! or Behold there! Do not go in search', which may be said of God's truth emanating from the Lord, but not of the Lord Himself.

[4] In the same gospel,

When the Son of Man comes will He find faith on the earth? Luke 18:8.

That is, when God's truth is revealed from heaven there will be no belief in it. Here also 'the Son of Man' is the Lord in respect of God's truth, or God's truth emanating from the Lord, the Lord's coming being the revelation of God's truth at the end of the Church.

[5] In Matthew,

As the lightning comes from the east and is seen as far as the west, so will the coming of the Son of Man be. Then the sign will appear, and then all the tribes of the earth will mourn; and they will see the Son of Man coming in the clouds of heaven with power and glory. Matthew 24:27, 30.

'The coming of the Son of Man' stands for the revelation of God's truth at the close of the age, that is, at the end of the Church. 'All the tribes of the earth' who will mourn then are all the truths and forms of the good of faith and love in their entirety that are derived from the Lord and so are offered to the Lord. 'The clouds of heaven' in which He is going to come are the literal sense of the Word, 'power and glory' being the internal sense, the subject of which at its inmost level is the Lord alone. For further explanation of these matters, see 4060.

[6] Something similar occurs elsewhere in the same gospel,

I say to you, Hereafter you will see the Son of Man seated on the right hand of power, and coming on the clouds of heaven. Matthew 26:64.

And in Luke,

Hereafter the Son of Man will be seated at the right hand of the power of God. Luke 22:69.

'The Son of Man' stands for Divine Truth emanating from the Lord. 'Sitting at the right hand of power' stands for the reality that in Him there is almighty power; for Divine Good exercises its almighty power through Divine Truth. The declaration that 'hereafter they would see this' means that Divine Truth would be in its almighty power, when the Lord in the world had overcome the hells and restored to order everything there and in the heavens, as a result of which those who received Him in faith and love could be saved, see 9715.

'Sitting at the right hand' means almighty power, see 3387, 4592, 4933 (end), 7518, 8281, 9133.

All the power good possesses is exercised through truth, 6344, 6423, 8304, 9327, 9410, 9639, 9643.

Actual Divine power consists in Divine Truth, 6948.

'The clouds' in which the Son of Man, that is, Divine Truth, will come are the Word in the letter, Preface to Genesis 18, and 4060, 4391, 5922, 6343, 6752, 8443, 8781; and 'the glory' is Divine Truth itself as it exists in the internal sense of the Word, Preface to Genesis 18, and 4809, 5922, 8267, 9429.

[7] All this now makes clear what the following words in the Book of Revelation mean,

I saw, and behold, a white cloud, and on the cloud one was sitting, like the Son of Man, having on His head a crown of gold. Revelation 14:14.

And in Daniel,

I saw in the night visions, and behold, with the clouds of the heavens One like the Son of Man came. Daniel 7:13.

In John,

The Father has given Him [authority] to execute judgement also, because He is the Son of Man. John 5:27.

The basis on which all judgement is executed is truth, and this explains why it says that [authority] to execute judgement has been given to the Lord because He is the Son of Man. 'The Son of Man', as has been stated, is Divine Truth; 'the Father' from whom that Truth springs is Divine Good, 2803, 3704, 7499, 8328, 8897. The fact that 'executing judgement' rests with Divine Truth explains why it says that when the Son of Man comes He will sit on the throne of His glory, Matthew 19:28; 25:31, and that the Son of Man will repay everyone according to his deeds, Matthew 16:27.

[8] In Matthew,

He who sows the good seed is the Son of Man, the field is the world, the seed are the sons of the kingdom, the tares are the sons of the evil one. Matthew 13:37-38.

'The good seed' is God's truth, therefore it says that 'the Son of Man' sows it. 'The sons of the kingdom' are God's truths in heaven and in the Church. For 'son' means truth, 489, 491, 533, 1147, 2623, and in the contrary sense falsity, which is also meant by 'son of the evil one'; and 'the kingdom' means heaven, and also the Church.

[9] In John,

No one has gone up into heaven except Him who came down from heaven, the Son of Man who is in the heavens. John 3:13.

From these words it is evident that 'the Son of Man' means Divine Truth present in the heavens. This Truth comes down from there and then goes up, for no one can go up into heaven unless Divine Truth has come down into Him from heaven; the flow starts from God, not from the opposite direction. And since the Lord is that Truth He calls Himself 'the Son of Man who is in the heavens'. In Matthew,

The Son of Man has nowhere to lay His head. Matthew 8:20.

'The Son of Man' stands for Divine Truth; 'having nowhere to lay His head' stands for the fact that at that time there was no place for Him anywhere, that is, with any person.

[10] The declarations that the Son of Man is about to suffer and will be killed, in Matthew 17:12, 22; 20:18; 26:2, 24, 45; Mark 8:31; 9:12, 31; and elsewhere, imply that this was how Divine Truth was treated, and therefore how the Lord was treated since He was Divine Truth itself, as He also says in John, I am the way, and the truth, and the life. John 14:6.

In Jeremiah,

No man (vir) will dwell there, nor will any son of man stay in it. Jeremiah 49:18, 33.

And in the same prophet,

Not a man (vir) will dwell in the cities, nor will any son of man pass through them. Jeremiah 51:43.

Anyone who has no knowledge of the spiritual sense of the Word will suppose that 'the cities' here is used to mean cities, and 'a man' and 'son of man' to mean a man and a son, and that the cities would be made so desolate that no one would be there. But it is the state of the Church so far as the teaching of truth is concerned that is being described. For 'cities' are the doctrinal teachings of the Church, see 402, 2449, 3216, 4492, 4493; 'a man' is the Church's truth itself joined to good, 3134, 7716, 9007, 'son of man' accordingly meaning truth.

[11] Since 'son of man' meant Divine Truth emanating from the Lord, the prophets too through whom it was revealed were called sons of man, as Daniel and Ezekiel were - Daniel 8:17; Ezekiel 2:1, 3, 6, 8; 3:1, 3-4, 10, 17, 25; 4:1, 16; 8:5-6, 8, 12, 15; 12:2-3, 9, 18, 22, 27; and in many other places.

[12] The majority of expressions in the Word have also a contrary sense, and this applies equally to the meaning of the expression son of man, which in that contrary sense is falsity opposed to truth, as in Isaiah,

What are you that you are afraid of man (homo), [who] dies, and of the son of man, [who] is given grass? Isaiah 51:12.

'Grass given to the son of man' is factual knowledge that gives rise to falsity. In David,

Do not put your trust in princes, in the son of man who has no salvation. Psalms 146:3.

'Princes' are primary truths, 2089, 5044, and so in the contrary sense primary falsities, while 'the son of man' is falsity itself.
