2231. 'That he will command his sons, and his house after him, and they will keep the way of Jehovah to do righteousness and judgement' means that from Him comes the entire doctrine of charity and of faith. This becomes clear from the meaning of 'son', 'house', 'way', 'righteousness', and 'judgement', which in short, or when their several meanings are converted into one, mean the entire doctrine of charity and of faith. For 'sons' means all who are governed by truths, 'house' all who are governed by goods, 'way' means the doctrine of faith which they are taught, 'righteousness' that doctrine in regard to good, 'judgement', in regard to truth. Doctrine regarding good is the doctrine of charity, while doctrine regarding truth is the doctrine of faith.

[2] In general there is only one doctrine, that is to say, the doctrine of charity, for, as stated in 2228, all things of faith have charity in view. No other difference exists between charity and faith than that which exists between willing what is good and thinking what is good - for one who wills what is good also thinks what is good - thus than that which exists between will and understanding. People who reflect on the matter know that the will is one thing and the understanding another. The same is also well recognized in the learned world, and it is plain to see in the case of those who will what is evil and yet from thought utter what is good. From such persons it is evident to anyone that the will is one thing and the understanding another, and thus that the human mind is divided into two parts which do not then make a single whole. Yet man was created in such a way that those two parts should constitute one single mind, and no other difference should exist between them than, to use a comparison, between that of a flame and the light shining from it. Love to the Lord and charity towards the neighbour were to be like the flame, and all perception and thought like the light shining from it. Thus love and charity were to constitute the whole of perception and thought, that is, to exist in every single part. Perception or thought regarding the essential nature of love and charity is that which is called faith.

[3] But because the human race started to will what was evil, to hate the neighbour, and to practice revenge and cruelty, with the result that the part of the mind called the will was completely corrupted, men started to make a distinction between charity and faith, and to attribute to faith all those matters of doctrine which belonged to their religion and to refer to them by the single term faith. At length they went so far as to say that people could be saved by faith alone, by which they meant their doctrine. They said that provided they believed that doctrine people could be saved no matter how they lived. Charity was accordingly separated from faith, and when that happens it is nothing else, to use a comparison, than some kind of light that has no flame, like sunlight in winter-time which is so cold and icy that the earth's vegetation languishes and dies. But faith that is derived from charity is like the light of spring-time and summer-time which causes all things to sprout and come into flower.

[4] The same may also be recognized from the fact that love and charity are celestial flame, while faith is the spiritual light that shines from it. This is also how faith and charity make a perceptible and visual presentation of themselves in the next life, for in that life the Lord's celestial manifests itself before the angels by means of a flaming radiance like that of the sun, while the Lord's spiritual manifests itself by means of the light shining from this; and that radiance and light act upon the angels and spirits interiorly according to the life of love and charity existing with them. This is the source of the joy and happiness in the next life with all their variations. These considerations show the implications of the assertion that faith alone saves.

2228. 'And in him all the nations of the earth will be blessed' means that from Him all who have charity will be saved. This is clear from the meaning of 'being blessed' as being endowed with all goods that have a heavenly origin, dealt with in 981, 1096, 1420, 1422. People who are endowed with goods from a heavenly origin, that is, with celestial goods and spiritual goods, which have been referred to immediately above in 2227, are also endowed with eternal salvation, that is, they are saved. 'All nations of the earth' is used to mean in the internal sense those with whom the goods exist that flow from love and charity, as is clear from the meaning of 'nation' as good, dealt with in 1159, 1258-1260, 1416, 1849. That 'all the nations of the earth' does not mean all people throughout the whole world may become clear to anyone, for there are so many among them who are not saved. Only those who have charity, that is, who have acquired the life of charity, are saved.

[2] So that the whole matter of the salvation of people after they have died does not remain hidden from anyone, let a brief discussion of it follow here. There are many who declare that man is saved through faith, or as they say, if he merely has faith. But the majority of such people do not know what faith is. Some imagine that it is mere thought; some that it is the acknowledgement of something which ought to be believed; others that it is the entire doctrine of faith, which ought to be believed; and others something different again. Thus in their mere knowledge of what faith is they are mistaken, and as a consequence they are mistaken as to what it is that saves a person. Faith however is not mere thought; nor is it the acknowledgement of something that ought to be believed; nor is it a knowledge of all that constitutes the doctrine of faith. Nobody can be saved by such thought, acknowledgement, or knowledge that cannot send down roots any deeper than thought. Thought does not save anyone, but the life which he acquires to himself in the world through the cognitions of faith. Such life remains, but all thought that is not in keeping with his life dies away, even to the point of becoming none at all. In heaven that which brings people into association with one another is their lives, not thoughts that are not related in any way to a person's life. Thoughts which are unrelated to a person's life are spurious and are totally rejected.

[3] In general there are two kinds of life, the first being the life of hell, the second that of heaven. The life of hell is derived from all those intentions, thoughts, and deeds that flow from self-love, consequently from hatred against the neighbour. The life of heaven is derived from all those intentions, thoughts, and deeds that belong to love towards the neighbour. This heavenly life is that to which all things called faith have regard and is acquired by means of all things of faith. From this it becomes clear what faith is, namely that it is charity, for all things that are said to be part of the doctrine of faith lead to charity. Charity embraces them all and from charity they are all derived. After the life of the body, the soul is such as its love is.
