In New Christian thought, “charity” has a significantly different meaning than in the common modern English definition. In Swedenborg's works "charity" is usually the English rendering of the Latin word "caritas", which is also the root of the verb “to care.” If we think of “charity” as “a state of caring,” we can start seeing what Swedenborg was trying to convey.

“Caring” does not necessarily have to be emotional. You can take care of someone you don’t like, you can take care of business or errands or duties that have little or no emotional content. Swedenborg would call these “acts of charity,” things done from a desire to be a good person. But the idea of “caring” can elevate, too: When you care about someone it involves real affection, and to care about an idea or mission implies a deep commitment - it is a feeling, an emotional state. The ultimate state of “caring,” of course, would be caring about all of humanity, wanting what’s best for everyone on the planet. This is what Swedenborg would call “true charity,” and it is marked by love - the love of others. Importantly, though, it can't be left as an abstraction; it needs to be grounded out in action.

Or as Swedenborg puts it in Arcana Coelestia 8033: “Charity is an inward affection consisting in a desire which springs from a person's heart to do good to the neighbour, which is the delight of his life.”

At all these levels, though, charity cannot act on its own. It needs tools.

Imagine, for instance, a young mother falling and breaking her leg. Her four-year-old might love her desperately, but cannot take care of her. A paramedic, meanwhile, might see her as just a case number, but will get her stabilized and delivered to a hospital. The difference, obviously, is knowledge. The paramedic has a bunch of tested, true ideas in her head that give her the capacity to care for the mother; the four-year-old does not.

That knowledge is actually part of what Swedenborg would call “faith,” though he’s referring to spiritual things rather than medical ones. In general, “faith” in Swedenborg’s works refers to not just belief in the Lord but also the things we accept as true because they come to us from the Lord and the Lord’s teachings. If we take them and apply them to life, we can do works of charity - we can use knowledge to take care of people and things, to actually do something good. For this reason, faith and charity are often linked in Swedenborgian theology.

And just like the idea of caring, these items of faith can elevate. “Thou shalt not murder” is a good low-level matter of faith, and should certainly be applied if we want to be charitable people. “Love thy neighbor as thyself” is a bit higher, a bit more internal, and will help us be charitable on a deeper level. The idea that by loving others we are loving the Lord will take us to a deeper place yet.

And perhaps most beautiful of all is what happens when we reach a state of true charity. If we work to be good because we want to serve the Lord, the Lord will eventually change our hearts, transforming us so that we delight in being good and delight in loving and helping others. At that stage the ideas of faith change from being the masters over our evil desires to being the servants of our good desires. From a loving desire to be good and serve others we will seek and use knowledge that lets us fulfill that mission.

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.
