Psalm 91 gives us strength. It shows how the Lord is with us, lifting us up, restoring us, and blessing us when we have made Him our dwelling place, and given Him our whole trust. Every verse outlines how strongly and surely the Lord defends and upholds us, no matter what we encounter or what we are required to go through.

There are vivid images: the Lord covers us with the feathers of His wings. His truth is our shield and buckler so that we need fear nothing. The Lord gives His angels charge over us, to keep us in all our ways, to bear us up lest we dash our foot against a stone.

This psalm also shows us the inner mind and state of Jesus in His life on earth. It points out particularly the times of the Lord's absolute confidence that He was God, and that His divine nature would protect Him in temptations. He could trust that all outcomes would be victorious, even when in deep anguish and conflict. (See Arcana Caelestia 2288.)

On a smaller scale, it's the same for us. We have our changing states -- our influences from heaven and from hell which lift us or oppress us. This psalm is a good one to read when we are down, but it also expresses our confidence in the Lord's power to bring us out of the "valley of despond". It reminds us, during a spiritual crisis, that the Lord has pulled us through before, and the He will do so again. (See Arcana Caelestia 5280.)

In Verse 4 the imagery is of feathers and wings. This is reminiscent of a bird hatching and sitting on its brood. Spiritually, it shows us the protective nature of all spiritual truth. Feathers are made of firmly-hooked filaments, and a feathered wing keeps dry when water (here representing falsity) lands on it. This image also evokes the Lord's love covering us and His providence over everything. (See Arcana Caelestia 8764[6])

The great theme in this psalm is the "equation" that no evil will have power over us because we have made the Lord our dwelling place. To know this, to feel this, to assert this, and to think about this is always restorative. It is the ultimate answer to all doubt and trial, to come into the presence of God in ourselves. This principle is attested in almost every phrase of this psalm. (See Apocalypse Revealed 883)

In Verse 1 the imagery is of the angels who have charge over us. Angels truly are with us, and they work with us for our spiritual wellbeing. They also represent the truths from the Word which are in our mind and heart, 'to keep you in all your ways'. The lion and the cobra stand for fierce and sudden attacks from evil spirits which aim to bring us down. The Word's truths will render them harmless. (See Heaven and Hell 391)

Note that the end of the psalm mentions the assurance of 'a long life'. This is not in terms of age or years but in dwelling in the Lord, and in the permanence, the eternity, of this.

883. "And He will dwell with them, and they shall be His people. And He Himself will be with them their God." This symbolizes their conjunction with the Lord, which is of such a nature that the people are in Him and He in them.

His dwelling with them symbolizes a conjunction of the Lord with them, as we will see below. The people's being His people, and His being with them their God, symbolically means that they are the Lord's, and that He is their Lord. Moreover, because dwelling with them symbolizes conjunction, it symbolically means that they will be in the Lord and have the Lord in them. Otherwise there is no conjunction. That this is the nature of the conjunction is clearly apparent from the Lord's words in John:

Abide in Me, and I in you... I am the vine, you are the branches. He who abides in Me, and I in him, bears much fruit; for without Me you can do nothing. (John 15:4-5)

And elsewhere:

At that day you will know that I am in My Father, and you in Me, and I in you. (John 14:20)

He who eats My flesh and drinks My blood abides in Me, and I in him. (John 6:56)

[2] The Lord's assuming a humanity and uniting it with the Divinity He had in Him from birth, which is called the Father, had as its goal a conjunction with people, as is apparent also in John:

For their sakes I sanctify Myself, that they also may be sanctified in the truth..., that they may be one as We are one: I in them, and You in Me. (John 17:19, 21-23, 26)

It follows from this that the conjunction is formed with the Lord's Divine humanity, that it is a reciprocal one, and that this is the only means of conjunction with the Divine called the Father.

[3] The Lord also teaches that the conjunction is formed by the Word's truths and by living in accordance with them (John 14:20-24; 15:7).

This, then, is what is meant by the Lord's dwelling with them and their being His people, and His being with them their God. So, too, elsewhere where the same words occur: Jeremiah 7:23; 11:4; Ezekiel 14:11; Jeremiah 24:7; 30:22; Ezekiel 11:20; 36:28; 37:23, 27; Zechariah 8:8; Exodus 29:45.

[4] To dwell with them symbolizes a conjunction with them because to dwell symbolizes conjunction out of love, as may be seen from many passages in the Word. It may be seen also from the abodes of angels in heaven. Heaven is distinguished into countless societies, all of them different from each other in accordance with the differences in their love's affections, in general and in particular. Each society embodies one particular variety of affection, and the people in it have dwellings distinct from each other, depending on how close or akin they are within that variety of affection, and those who are the most closely related dwell together in the same house. Dwelling together, therefore, when said of married partners, symbolizes in the spiritual sense conjunction by love.

It should be known that conjunction with the Lord is not the same as His presence. Conjunction with the Lord is possible only with people who turn to Him directly, His presence with everyone else.
