Part of the Christian message is the concept of redemption. What does it mean, to say that the Lord redeemed people?

Here are the key concepts about redemption in New Christian thought, as excerpted from Swedenborg's works (written in the 1700s):

"Jehovah God came down and took upon Himself a human form, in order to redeem and save mankind.

Christian churches today believe that God the Creator of the universe fathered a Son from eternity, who came down and took upon Himself human form to redeem and save mankind. But this is an error and collapses of its own accord, so long as the mind concentrates on the oneness of God, and the reason looks upon as fiction or worse the idea that the one God fathered a Son from eternity, and also that God the Father together with the Son and the Holy Spirit, each of whom is severally God, is one God. This fiction is utterly exploded, like a meteorite in the atmosphere, when it is shown from the Word that it was Jehovah God Himself who came down and became man and also was the Redeemer." (True Christian Religion 82)

"In the process of taking on a human manifestation, God followed his own divine design.... Now, because God came down, and because he is the design..., there was no other way for him to become an actual human being than to be conceived, to be carried in the womb, to be born, to be brought up, and to acquire more and more knowledge so as to become intelligent and wise. Therefore in his human manifestation he was an infant like any infant, a child like any child, and so on with just one difference: he completed the process more quickly, more fully, and more perfectly than the rest of us do." (True Christian Religion 89)

"There is a belief that the Lord in his human manifestation not only was but still is the Son of Mary. This is a blunder, though, on the part of the Christian world. It is true that he was the Son of Mary; it is not true that he still is. As the Lord carried out the acts of redemption, he put off the human nature from his mother and put on a human nature from his Father. This is how it came about that the Lord's human nature is divine and that in him God is human and a human is God.' (True Christian Religion 102)

"Suffering on the cross was the final trial the Lord underwent as the greatest prophet. It was a means of glorifying his human nature, that is, of uniting that nature to his Father's divine nature. It was not redemption. There are two things for which the Lord came into the world and through which he saved people and angels: redemption, and the glorification of his human aspect. These two things are distinct from each other, but they become one in contributing to salvation.

In the preceding points we have shown what redemption was: battling the hells, gaining control over them, and then restructuring the heavens. Glorification, however, was the uniting of the Lord's human nature with the divine nature of his Father. This process occurred in successive stages and was completed by the suffering on the cross." (True Christian Religion 126)

"Redemption consisted in the conquest of the hells, the ordering of the heavens and the establishment of a new church, because without them no one could have been saved. This is their proper order: the hells had first to be conquered, before a new heaven of angels could be formed, and this had to be formed before a new church could be established on earth. For people in the world are so linked with the angels in heaven and the spirits in hell, that in the interiors of their minds they are identified with one party or the other." (True Christian Religion 115)

"Without that redemption no man could have been saved, nor could the angels have continued in a state of integrity. It shall be told first what redemption is. To redeem means to liberate from damnation, to deliver from eternal death, to rescue from hell, and to release from the hand of the devil the captive and the bound. This the Lord did by subjugating the hells and establishing a new heaven." (True Christian Religion 118)

120. There were many reasons why, but for redemption by the Lord, injustice and wickedness would have spread throughout the Christian peoples in either world, spiritual as well as natural. One of these is that everyone after death comes into the world of spirits, and is then exactly like what he was before. No one on arrival can be prevented from talking with his dead parents, brothers, relations and friends. Every husband then first seeks out his wife, every wife her husband. By these contacts of both kinds they are brought into the company of people who look outwardly like sheep, but inwardly resemble wolves. They are able to corrupt even those who led religious lives. Thus, as a result of unspeakable tricks unknown in the natural world, that world is filled with wickedness, like a pool covered with a green slime of frogs' spawn.

[2] The effect of keeping bad company there can be rendered plain to view by considering these parallels. If a person spends his time with thieves or pirates, he ends up by becoming like them; if he lives with adulterers and whores, he ends up by thinking adultery of no consequence. Again if he mixes with terrorists, he ends up by thinking nothing of using violence on anyone. All evils are contagious, and can be likened to a plague which infects people simply by their being exposed to the victims' breath; or to a cancer or gangrene which spreads, and makes first the surrounding parts, and then those further and further away, rot, until the whole body is destroyed. It is the pleasures of evil, to which everyone is prone from birth, that cause this.

[3] Now these facts will establish that but for the redemption effected by the Lord no one could be saved, nor could the angels remain unharmed The sole refuge to avoid destruction is to betake oneself to the Lord, for He says:

Remain in me, and I in you. Just as the branch can bear no fruit by itself, but only if it remains part of the vine, so neither can you, unless you remain in me. I am the vine, you are the branches. He who remains in me and I in him bears much fruit, because without me you can do nothing. Unless a person abides in me, he is cast out and withers, and is thrown into the fire and burnt, John 15:4-6.
