In John 14:6, 'the way' is doctrine, 'the truth' is every thing pertaining to doctrine, and 'the life' is the essential good which is the life of truth.

1974. As for the meaning of "evening and morning," in all phases of regeneration, both general and particular, the progression starts from evening, and tends toward morning. In general, the evening of those who are being regenerated is misery, temptations, despair, but they arrive at the morning. So also in detail, in all phases of regeneration one begins from evils, which are turned into good. And it is worth remembering that evil spirits begin, out of their own fantasies and passions, to arouse the person, but that these evils are turned into good in various ways. This has been revealed to me by experience lasting 3 years. So that is "evening and morning," and it applies to every least phase. Therefore it is the process not only of regeneration, but also of the perception of goodness. 1748, 16 May.
