2144. 'In the oak-groves of Mamre' means the character of the perception. This is clear from the representation and meaning of 'oak-groves', and also from the representation and meaning of 'Mamre'. What oak-groves in general represented and meant has been shown in Volume One, in 1442, 1443, and what the oak-grove of Mamre specifically represented and meant, in 1616, namely perceptions, though of a human kind such as spring from factual knowledge and from the initial rational concepts derived from that knowledge.

[2] What perception is, is totally unknown at the present day, for nobody today possesses the kind of perception that the ancient and especially the most ancient people possessed. The latter knew from perception whether a thing was good and consequently whether it was true. There was an influx from the Lord by way of heaven into the rational part of their minds, and from that influx when they thought about anything holy, they perceived instantly whether a thing was so or was not so. Later on such perception with mankind perished and people began to entertain heavenly ideas no more but only worldly and bodily ones; and when this happened the place of such perception was taken by conscience (which also is a kind of perception), for acting contrary to conscience and according to conscience is nothing else than discerning from conscience whether a thing is so or not so, or whether it ought to be done.

[3] But perception that goes with conscience does not originate in inflowing good but in truth which from earliest childhood has been implanted in the rational part of the mind in accordance with the holiness of people's worship, and after that has been confirmed; for that truth alone is believed by them to be good. Consequently conscience is a kind of perception, but it has its origin in truth such as this; and when charity and innocence are introduced into it by the Lord, the good that goes with that conscience is then brought into being. These few considerations show what perception is. Yet between perception and conscience there is a wide difference. See what has been stated about perception in Volume One, in 104, 125, 371, 483, 495, 503, 521, 536, 597, 607, 784, 865, 895, 1121, 1616; about the perception spirits and angels have, in 202, 203, 1008, 1383, 1384, 1390-1392, 1394, 1397, 1504; and about the learned not knowing what perception is, in 1387.

[4] As regards the Lord when He lived in the world, all of His thought sprang from Divine perception since He alone was a Divine and Celestial Man. For He has been the only one in whom Jehovah Himself was present and from whom His perception came, also dealt with in Volume One, in 1616, 1791. His perceptions became more and more interior the closer He came to union with Jehovah. The nature of His perception at this time becomes clear from what has been stated in Volume One, in 1616, about the oak-groves of Mamre; and then the nature of it when He perceived the things contained in this chapter is described in what follows below.

598. 'He found grace in Jehovah's eyes' means that the Lord foresaw that the human race could in that way be saved. The mercy of the Lord entails and looks to the salvation of the whole human race; and so does His grace. Consequently, the salvation of the human race is meant. 'Noah' means not only a new Church but also the faith of that Church, which was a faith that inhered in charity. The Lord accordingly foresaw that it would be possible for the human race to be saved by means of faith that inhered in charity. Such faith will be dealt with later on.

[2] In the Word however a distinction is made between mercy and grace, a distinction which depends in fact on differences in those who are their recipients. Mercy applies to those who are celestial, but grace to those who are spiritual, for celestial people acknowledge nothing other than mercy, while spiritual acknowledge hardly anything other than grace. Celestial people do not know what grace is, while the spiritual scarcely know what mercy is, for they make mercy and grace to be one and the same. The reason for the difference springs from each one's humility. People in whom there is humility of heart plead for the Lord's mercy, but those in whom there is humility of mind (cogitatio) seek His grace. Or if the latter do plead for mercy they do so in a state of temptation or with the lips only and not with the heart. Since the new Church called Noah was not celestial but spiritual, it is not said to have found mercy but to have found grace in Jehovah's eyes.

[3] The distinction made in the Word between mercy and grace is clear from very many places where Jehovah is said to be merciful and gracious, as in Psalms 103:8; 111:4; 112:4; Joel 2:13. The same distinction is made elsewhere, as in Jeremiah,

Thus said Jehovah, The people which were left of the sword found grace in the wilderness, when He went to give rest to Israel. From afar Jehovah appeared to me. I have loved you with an everlasting love; therefore I have drawn you with mercy. Jeremiah 31:2-3.

Here 'grace' has reference to what is spiritual and 'mercy' to what is celestial. In Isaiah,

Therefore Jehovah will wait to grant you grace, and therefore He will exalt Himself to be merciful to you. Isaiah 30:18.

Here similarly 'grace' has regard to what is spiritual and 'mercy' to what is celestial. And further on [in Genesis] where Lot is addressing the angels,

Behold now, Your servant has found grace in Your eyes, and You have magnified Your mercy which You have shown to me in causing my soul to live. Genesis 19:19.

Here also it is clear that since he is spoken of as 'having found grace in Your eyes' grace has regard to spiritual things which are matters of faith or of the understanding. And since the expressions 'to have magnified mercy' and 'to have caused my soul to live' are used, it is equally clear that mercy has regard to celestial things, which are matters of love or of the will.
