In chapter 4 of the Book of Amos, verses 1-3 are talking about people who pervert the truths of the church. They will fall into falsities in outermost things.

In the Bible, fish represent "lower" things than mammals, so we can interpret the fishhooks in verse 2 as meaning being caught and held fast in natural or lower things.

Verses 4-6 are about acts of worship such as tithes and sacrifices. These look similar to genuine worship, but are only external sorts of things. We can tell because ‘teeth’ (in verse 6) represent ultimates or outermost things (see Secrets of Heaven 6380). It follows that “cleanness of teeth” would mean outermost things that look good but only imitate genuine worship. The Lord exhorts, “Yet you have not returned to me.”

Verses 7-8. Some things true will remain, when where there are too many false ideas, the truths don't get through. This can be seen where the Lord says, “I made it rain on one city; I withheld rain from another city... where it did not rain the part withered.” Again the Lord exhorts, “Yet you have not returned to me.”

Verse 9. Afterward all things of the church are falsified, shown by blight attacking the gardens, vineyards, fig tree and olive trees. The last three represent spiritual, natural and celestial things, or all the things of spiritual life. “Yet you have not returned to me,” says the Lord.

Verses 10-11. The Lord explains the devastating things he allowed to happen: plague in Egypt, death of young men by swords, stench in the camps, Sodom and Gomorrah. This is because they are profaned by sensual knowledges. Profanation means the mixing of good and evil together. (See Secrets of Heaven 1001[2]).

This extends to all things of the church, with the church being the Lord’s kingdom on earth (Secrets of Heaven 768[3]).

With profanation “as soon as any idea of what is holy arises, the idea of what is profane joins immediately to it,” (Secrets of Heaven 301).

Now there is hardly anything left. “Yet you have not returned to Me,” says the Lord again.

Verses 12-13: Because people adamantly remain in their profane ways, they are warned, “Prepare to meet your God!”. This is the God powerful and mighty, “who forms mountains, and creates the wind,” and even more close to home, “Who declares to man what his thought is.” As intimately a knowing as that is, the Lord’s love for all humanity is contained in His exhortations for them to turn themselves to Him.

See, for example, Luke 6:44-45, and True Christian Religion 373.

372. (iv) This reciprocal link between the Lord and man is created by means of charity and faith.

It is known at the present time that the church constitutes the body of Christ, and that each individual, in whom the church is, is in some member of that body, as Paul says (Ephesians 1:23; 1 Corinthians 12:27; Romans 12:4-5). But what is the body of Christ but Divine good and Divine truth? This is what is meant by the Lord's words in John:

He who eats my flesh and drinks my blood remains in me and I in him, John 6:56.

The Lord's flesh means Divine good, as bread does too; His blood means Divine truth, as wine does too; for these meanings, see the chapter on the Holy Supper [698-752].

[2] It follows from this that in so far as a person is in possession of the kinds of good which make up charity and the truths which make up faith, so far is he in the Lord and the Lord is in him. For linking with the Lord is spiritual linking, and this takes place solely through charity and faith. It was shown in the chapter on the Sacred Scripture (248-253) that every detail of the Word contains a linking of the Lord and the church, and so of good and truth; and because charity is good and faith is truth, there is at every point in the Word a linking of charity and faith. From these propositions it now follows that the Lord is charity and faith in a person, and a person is charity and faith in the Lord. For the Lord is the spiritual charity and faith in a person's natural charity and faith, and a person is the natural charity and faith coming from the Lord's spiritual charity and faith. These when linked constitute spiritual-natural charity and faith.
