51. As regards what the image is, an image is not a likeness but is 'according to a likeness'. Therefore it is said, 'Let Us make man in Our image, according to Our likeness'. A spiritual man is an image, whereas a celestial man is a likeness or exact replica. The spiritual man is the subject in this present chapter, the celestial man in the next. The spiritual man, who is an image, is called by the Lord 'a son of light', as in John,

He who walks in the darkness does not know where he is going. While you have the light, believe in the light, that you may be sons of light. John 12:35-36.

He is also called 'a friend',

You are My friends if you do whatever I command you. John 15:14-15

The celestial man however, who is a likeness, is called 'a son of God', in John,

As many as received Him, to them He gave power to be sons of God, to those believing in His Name, who were born, not of blood, ¹ nor of the will of the flesh, nor of the will of man, but of God. John 1:12-13.

424. This ability to think from the understanding and not at the same time from the will is provided that man may be capable of being reformed; for reformation is effected by means of truths, and truths pertain to the understanding, as just said. For in respect to his will man is born into every evil, and therefore of himself wills good to no one but himself; and one who wills good to himself alone delights in the misfortunes that befall another, especially when they tend to his own advantage; for his wish is to divert to himself the goods of all others, whether honors or riches, and so far as he succeeds in this he inwardly rejoices. To the end that this will of man may be corrected and reformed, an ability to understand truths, and an ability to subdue by means of truths the affections of evil that spring from the will, are given to man. This is why man has this ability to think truths with his understanding, and to speak them and do them. But until man is such that he wills truths and does them from himself, that is, from the heart, he is not able to think truths from his will. When he becomes such, whatever he thinks from his understanding belongs to his faith, and whatever he thinks from his will belongs to his love; and in consequence his faith and his love, like his understanding and his will, are conjoined in him.
