9215. 'It is his clothing for his skin' means that they also clothe relatively external things. This is clear from the meaning of 'clothing' as the sensory level in general or things on that level, as above; and from the meaning of 'skin' as that which is relatively external, which also clothes more internal things but still exists within those on the sensory level. What 'the skin' means, and who exactly correspond to the skin in the next life, see 3540, 5552-5559, 8977, 8980. The natural degree of the human mind has a rather internal level, a relatively external or middle level, and an outermost level. The more internal level of the natural is in contact with heaven; the middle or relatively external level is in contact on one side with the more internal, and through this with heaven, and on the other side with the outermost, and through this with the world, see 4009, 4570, 5118, 5126, 5497, 5649, 5707. The outermost level of the natural is that of the senses, which is meant here by 'clothing'. This level receives impressions of objects in the world and thereby serves more internal things. It is called 'his only covering' because it is the last and lowest and so is general to all, the relatively external or middle level of the natural being the one meant by 'skin'. From this it is evident that 'his clothing for his skin' means that the sensory level also clothes relatively external things. The fact that the sensory level is the last and lowest of a person's life, and so is a general covering, see 4009, 5077, 5125, 5128, 5767, 5774, 6201, 6313, 7442, 7693.

2853. 'In your seed all the nations of the earth will be blessed' means the salvation of all who are endowed with good. This is clear from the meaning of 'being blessed' as being enriched with celestial and spiritual good (dealt with in 981, 1096, 1420, 1422) and - since those who are saved are the subject - as being saved, for as is well known 'being blessed' has a wide range of meanings; from the meaning of 'seed' as faith that is the expression of charity, dealt with in 1025, 1447, 1610; and from the meaning of 'the nations of the earth' as those who are endowed with good, dealt with in 1159, 1258-1260, 1416, 1849.

[2] In addition to this, these words contain the following arcanum: By means of the Church, meant here by 'the earth', 662, 1066, 1068, 1262, those people are saved who are outside of the Church, for 'your seed', as has been stated, means faith that is the expression of charity. Faith that is the expression of charity occurs only with those within the Church since such faith is in essence truth taught by doctrine coupled to goodness of life. For the truth of the matter is that the Lord's kingdom on earth consists of all those who are endowed with good, who, though spread throughout the whole world, are nevertheless one, and as members constitute one body. The same is so with the Lord's kingdom in the heavens. There the whole of heaven presents itself as one entire human being, which is for that reason also called the Grand Man, 684, 1276. And what is a marvel and unknown until now, all parts of the human body correspond to communities in heaven. For this reason it is sometimes said that this group of communities belong to the province of the head, that group to the province of the eye, another group to that of the chest, and so on. This correspondence will in the Lord's Divine mercy be discussed in a section by itself.

[3] It is similar with the Lord's Church on earth. Here the Church is like the heart and lungs, and those outside of the Church resemble parts of the body which are sustained by, and get their life from, the heart and lungs. From this it is evident that without the Church somewhere on earth the human race cannot continue to exist, even as the body cannot without the heart and lungs in it, see 468, 637, 931, 2054. It is for this reason that as often as any Church reaches its end, that is, ceases to be a Church because no charity exists any more, the Lord in His Providence always raises up a new one. When for example the Most Ancient Church, which was called Man, perished, the Lord created a new one, which was referred to as Noah. This was the Ancient Church, which existed after the Flood. And when this declined and became no longer a Church, the Jewish and Israelite representative Church was brought into being. And when this became wholly extinct the Lord came into the world and again established a new one. This was done by Him to the end that heaven might be joined to the human race by means of the Church. This is also what is meant by the words 'in your seed all nations of the earth will be blessed'.
