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:

3986. 'And Jehovah has blessed you since I set foot here' means resulting from the Divine endowment which the natural possessed. This is clear from the meaning of 'Jehovah blessing' as being endowed with good, dealt with in 3406, and as a joining together, 3504, 3514, 3530, 3565, 3584. 'Jehovah blessing' accordingly means being endowed with Divine good by means of a joining together, at this point a joining to the good of the natural represented by 'Jacob', the natural being meant by 'the foot'. As regards 'the foot' meaning the natural, see 2162, 3147, 3761; and this will be clear in addition from the correspondence of the Grand Man with every part of the human being, the subject in the sections at the ends of chapters. From this it is evident that 'Jehovah has blessed you since I set foot here' means originating in the Divine which the natural possessed.

[2] The arcanum which lies concealed in these words and in those immediately before them is known to few, if any, and is therefore to be revealed. The goods present with people both inside the Church and outside it vary in every case. They vary so much that no one person's good is ever exactly like another's. These variations arise out of the truths to which those goods are joined, for the nature of every type of good is received from truths, and truths derive their essential nature from goods. Such variations also arise out of the affections that belong to each person's love, and which become rooted in a person and are made his own through the life he leads. Few genuine truths exist even with someone inside the Church, and fewer still with one outside. Consequently affections for genuine truth seldom exist with anyone.

[3] All the same, people who lead good lives, that is, who live in love to God and in charity towards the neighbour, are saved. The reason they are able to be saved is that the Lord's Divine is present within good that stems from love to God and within good that stems from charity towards the neighbour. And when the Divine is inwardly present everything is being arranged into order so that it can be joined to genuine goods and genuine truths which exist in the heavens. The truth of this may be proven from the communities constituting heaven, which are countless. Every single community varies as regards good and truth, and yet all of them taken together form one complete heaven. They are like the members and organs of the human body which, though varying in every case, still constitute one complete human being. For no complete whole is ever made up of any identical or entirely similar individual parts, but of varying parts harmoniously joined together. Varying parts joined together harmoniously present a single whole. The same applies to goods and truths in the spiritual world. Although these vary so much as never to be exactly similar with one person as with another, nevertheless from the Divine through love and charity they make one since love and charity are spiritual conjunction. Their variation is a heavenly harmony which produces such accord that they are one in the Divine, that is, in the Lord.

[4] Furthermore, however much truths may vary, and however much affections for truth may do so, good that stems from love to God and good that stems from charity towards the neighbour are nevertheless capable of receiving genuine truth and good, as they are not so to speak hard and resistant but soft and yielding. They allow themselves to be led by the Lord and in so doing to be turned towards good, and through good to be turned towards Him. It is different with those in whom self-love and love of the world reign. They do not allow themselves to be led and turned by the Lord towards the Lord but strongly resist, since each wishes to be his own leader, even more so when they have become subject to false and firmly established assumptions. As long as they are such they do not allow the Divine to come in.

[5] These considerations now make clear what is meant in the internal sense by these words which Jacob addressed to Laban, for 'Laban' means the kind of good which is not genuine because it does not have genuine truths planted within it but is nevertheless capable of having these joined to it and of having the Divine present within it. This kind of good is what normally exists with young children before they have received genuine truths. It is also the kind of good present with simple people within the Church who know few truths of faith but who nevertheless lead a charitable life. It is in addition the kind of good present with upright gentiles who offer holy worship to their gods. By means of such good, genuine truths and goods are able to be introduced, as may be seen from what has been stated about young children and simple people inside the Church in 3690, and about upright gentiles outside the Church in 2598-2603.
