Like so many common verbs, the meaning of "know" in the Bible is varied and dependent on context. And in some cases -- when it is connected to ideas or objects -- its spiritual meaning and natural meaning are essentially the same. When the Bible talks about people knowing each other and especially when it talks about the Lord knowing people, the meaning has more to do with the states of love within people than it does with any factual knowledge. This makes sense if you think about it. When we really "know" somebody, what we mean is that we know what kind of person they are, what their motivations are, what they love, what they hate, what makes them tick. Those things are far more important than knowing their parents' names, where they were born or what year they graduated from school. Most often then, especially applied to people, "knowing" has to do with the perceptions we have about other people's loves and the conjunction that can exist between those with similar loves, not just a collection of facts.

875. 'The dove found no rest for the sole of its foot' means that no good and truth of faith at all had as yet been able to take root. This is clear from the meaning of 'a dove' as the truth of faith, and also from the meaning of 'rest for the sole of the foot' as taking root. The reason why they cannot take root is stated further on, namely that falsities were still there to overflowing. But nobody can begin to understand what all this means unless he knows how the regeneration of the spiritual man is accomplished.

[2] With this man the cognitions of faith drawn from the Word of the Lord - that is, matters of doctrine drawn from that source, which the Ancient Church had from what had been revealed to the Most Ancient Church - had to be planted in his memory, and in this way the understanding part of his mind received instruction. But as long as falsities dwell there to overflowing, truths of faith cannot take root, even though they have been planted there. They remain solely on the surface, or in the memory. Nor, as stated already, does the ground become suitable until falsities have been so dispersed that they do not reappear.

[3] The ground itself with this person is made ready in the understanding part of his mind, and when it has been made ready good that stems from charity is planted in it by the Lord, and through charity conscience from which he then acts, that is, by means of which the Lord produces in him the good and truth of faith. Thus the Lord separates in this man things belonging to his understanding from those belonging to his will in such a manner that they are in no way united. For if they were united he would inevitably and eternally perish.

[4] With the member of the Most Ancient Church things of the will had been united to those of the understanding, as they are with celestial angels too. But with the member of this Church they were not united, nor are they united with the spiritual man. It still seems as though the good of charity which he does is the product of his will, but that is solely an appearance and illusion. All the good of charity which he does is the Lord's alone, coming not by way of the will but of conscience. If the Lord were to let up only slightly and allow a person to act from his own will, he would, from hatred, revenge, and cruelty, perform evil instead of good.

[5] The same applies to the truth which a spiritual man thinks and speaks. Unless he thought and spoke from conscience, and so from good that is the Lord's, he could no more think and speak what is true than the devil's crew when impersonating angels of light. This is perfectly obvious in the next life. From these considerations it is clear how regeneration is accomplished and what the regeneration of a spiritual man is. It is the separation of the understanding part of his mind from the will part by means of conscience, which is formed by the Lord in that understanding part. What is performed in this manner seemingly springs from his own will, but in fact it does so from the Lord.
