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.

1420. 'You will be a blessing' means that every single thing comes from the Lord. This becomes clear from the meaning of 'a blessing'. Blessing has reference to every form of good - in the external sense to bodily, worldly, and natural forms, in the internal sense to spiritual and celestial forms. 'Being a blessing' means the Source of every form of good and the Giver of this, an attribution that cannot possibly be made to Abram. From this it is also clear that 'Abram' represents the Lord, who alone is a Blessing. So also with the attributions made to Abraham further on, such as,

Abraham will surely become a great and numerous nation, and in him all the nations of the earth will be blessed. Genesis 18:18.

Concerning Isaac,

In your seed will all the nations of the earth be blessed. Genesis 26:4.

And concerning Jacob,

In you all the families of the earth will be blessed, and in your seed. Genesis 28:14.

That nations are not able to be blessed, nor were they blessed, in Abraham, Isaac, and Jacob, and in their seed, but that they were blessed in the Lord, may become clear to anyone. This is clearly stated in David,

His name will be for ever, before the sun His son's name; and all nations will be blessed in Him Psalms 72:17.

This refers to the Lord. In the same author,

You set Him to be blessings for ever. Psalms 21:6.

This also refers to the Lord. In Jeremiah,

In Him the nations will be blessed, and in Him will they glory. Jeremiah 4:2.

From these places it is now clear that 'a blessing' means the Lord, and when He is called a Blessing that it means that from Him come all celestial and spiritual things which alone are goods. And because they alone are goods they alone are truths as well. To the extent therefore that celestial and spiritual forms of good are present in natural, worldly, and bodily forms, the latter are good and are blessed.
