In a casual reading, the story at the beginning of Luke chapter 9 doesn't seem to have much relation to the events of the previous chapter. But, looking deeper, it does.

At the end of Luke chapter 8, when the little girl who seemed to be dead was brought back to life, Jesus commanded that her parents give her something to eat. In sacred scripture, giving someone “something to eat” is about spiritual nourishment. It refers not only to teaching, but also spiritually nourishing one another with words of encouragement that align with spiritual truth. To the extent that we do this for one another, we become God’s disciples and apostles, cooperating with Him in the work of salvation. We are “disciples” while in His presence, learning from His Word. And we are His “apostles” when we are being sent out to minister to others, through our words and actions.

It's appropriate, then, that chapter 9 begins with Jesus calling together His twelve disciples, and then sending them out to minister to others:

“Having called together His twelve disciples, He gave them power and authority over all demons, and to cure diseases. And He sent them out to preach the kingdom of God, and to heal the sick” (Luke 9:1-2).

In a deep sense, the gathering together of the twelve disciples, before sending them out as apostles, represents an important step in our spiritual development. This begins when Jesus “calls His twelve disciples together” in us, which represents that time in our lives when we begin to understand matters of the spirit more deeply. Every “disciple” represents an essential spiritual principle. As we “gather” these principles together in our minds, striving to see how they cohere and relate to the larger whole, we begin to see the connections between ideas, and we develop a keener discernment between what is primary and what is secondary. As a result, we can apply the truth we have been learning more usefully in our lives. ¹

After gathering the disciples together, Jesus sends them forth as His apostles, giving them specific instructions for the journey. “Take nothing for your journey,” He says to them. They are not to take a staff, or a backpack, or bread, or silver, or even an extra change of clothes. Every word has spiritual significance. They will not be needing a “staff,” because they will be relying on the Lord alone. They will not need a “pack” to store up what they have learned, because the Lord will give them what to say. They will not need “bread” or “silver,” because the Lord will provide all the goodness (“bread”) and all the truth (“silver”) they need. And they will not need an extra tunic because they will be clothed in truth from the Lord, and will not need anything additional from themselves.

In this case, less is more. When there is less of self, there is more of God. ²

Shaking off the dust:

Jesus then says to them, “And into whatever house you enter, there remain, and thence go out. And as many as shall not accept you, when you come out of that city, shake off even the dust from your feet for a testimony against them” (Luke 9:4-5). A “house,” as we have mentioned before, represents the human mind. It is the place where we think things over, consider our options, and dwell on those matters that are significant to us. Our “house,” then, is our spiritual residence, our “dwelling-place.”

Spiritually speaking, everyone has a dwelling-place — a set of beliefs about themselves, about others, and about God. Because of this, some people will accept the teachings of the apostles gladly, while others will reject them. Knowing this in advance, Jesus tells them that if their teachings are rejected, the apostles should leave the house, come out of the city, and “shake the dust from off their feet.”

In sacred scripture, the term “dust” refers to things that are low and relate to the world of the external senses. Just as dust settles to the earth, there is a tendency to remain focused on things that gratify our worldly senses without lifting our minds to higher things. In the Hebrew Scriptures, this is represented by the lowly serpent who deceived Eve. As it is written, “So the Lord God said to the serpent, “Because you have done this … you shall eat dust all the days of your life” (Genesis 3:14). ³

Jesus’ instruction to “shake off the dust” is sound advice, not only for the apostles, but for each of us. Along the spiritual journey, as we are learning truth and putting it into our lives, we may, at times, find ourselves being dragged down to lower things — those things that are merely worldly and temporal. This is, spiritually, “the dust on our feet.” Whether the dust comes through the negative influence of others or the self-serving thoughts we entertain, Jesus tells us to “shake the dust from off our feet,” and continue our journey. ⁴

This is precisely what the apostles do. As it is written in the next verse, “And going out, they passed into the villages, announcing the gospel and curing everywhere” (Luke 9:6).

Footnotes:

3488. The fact that these words spoken by the Lord and recorded in the gospel describe the second state of the perversion of the Church is evident from their internal sense, which is as follows,

All these are the beginning of sorrows means the things that have already happened, that is to say, the things that belong to the first state of the perversion of the Church, which, as has been stated, takes place when people cease to know any longer what goodness is and what truth is and start to argue with one another about them, with the result that falsities, and consequently heresies arise. The fact that such things perverted the Church before very many centuries had gone by is evident from the consideration that the Church in the Christian world became divided, and that its divisions were the result of opinions concerning goodness and truth; so that the Church began to be perverted a long way back in the past.

[2] At that time they will deliver you up to affliction, and will kill you means that goodness and truth will perish, at first through 'affliction'- that is, through perversion - and then through men 'killing' them, that is, through denial. For 'killing', when used in reference to goodness and truth, means that these are not being accepted, and thus that people deny them, see 3387, 3395. 'You' - the apostles - means all things of faith in their entirety, and so means the good of faith as well as the truth of faith; for the twelve apostles meant those things, see 577, 2089, 2129, 2130 (end), 3272, 3354. Here it is quite evident that they have that meaning, for the subject is not the preaching of the apostles but the close of the age.

[3] And you will be hated by all nations for My name's sake means contempt for and loathing of everything to do with goodness and truth. 'Hating' is holding in contempt and loathing, for these are manifestations of hatred. 'By all nations' means by persons under the influence of evil, for 'nations' refers to these, see 1259, 1260, 1849, 1868, 2588 (end). 'For My name's sake' is for the Lord's sake, and so for the sake of everything that comes from Him - 'the Lord's name' being everything in its entirety by which He is worshipped, and so everything belonging to His Church, see 2724, 3006.

[4] At that time many will stumble, and betray one another, and hate one another means hostility on account of those things. 'Many will stumble' means the hostility in itself - the Lord's Human being that against which the hostility is directed. That this will be a cause of offence or a stumbling-block is foretold in various places in the Word. 'Betray one another' is hostility towards one another arising out of falsity conflicting with truth. 'And hate one another' is hostility towards one another arising out of evil conflicting with good.

[5] And many false prophets will arise and will lead many astray means declarations of falsity - 'false prophets' meaning teachers of falsities, thus false doctrine, see 2534. 'And will lead many astray' means that there will be things that are the issue of that doctrine.

[6] And because iniquity is multiplied the charity of many will grow cold means charity together with faith breathing its last. 'Because iniquity is multiplied' means in keeping with falsities of faith. 'The charity of many will grow cold' means charity breathing its last; for the two - charity and faith - go together side by side. Where there is no faith there is no charity; and where there is no charity there is no faith. Charity however is that which receives faith, and the absence of charity is that which rejects faith. This is the origin of all falsity and of all evil.

[7] But he who endures to the end will be saved means the salvation of those who have charity. 'He who endures to the end' is the person who does not allow himself to be led astray, and so does not yield in times of temptation.

[8] And this gospel of the kingdom will be preached in the whole inhabited earth as a testimony to all nations means that the Christian world will be the first to come to know it. 'Will be preached' means that it will come to be known. 'This gospel of the kingdom' is this truth, that it really is so - 'gospel' being pronouncement, 'the kingdom' truth, for 'the kingdom' means truth, see 1672, 2547. 'In the whole inhabited earth' is the Christian world, 'the earth' being that region where the Church, and so the Christian world, is, see 662, 1066, 1068, 1262, 1733, 1850, 2117, 2118, 2928, 3355. Here the Church is called 'the inhabited earth' from the life of faith, that is, from the good that dwells in truth, for 'inhabiting' in the internal sense is living, and 'inhabitants' are the goods that dwell in truth, 1293, 2268, 2451, 2712, 3384. 'As a testimony' means to ensure that they know, and to prevent them pretending that they do not know. 'To all nations' means to the evil, 1259, 1260, 1849, 1868, 2588. For when people are under the influence of falsity and evil they no longer know what truth is or what good is; indeed they believe that falsity is truth, that evil is good, and vice versa. When the Church reaches this state, at that point the end will come. The words that follow next, to be explained in the Lord's Divine mercy in the preliminary section of the next chapter of Genesis, deal with that state of the Church which is called 'the abomination of desolation', which is the third state.
