The faith of the new heaven and the new church is stated here in both universal and specific forms to serve as the face of the work that follows, the doorway that allows entry into the temple, and the summary that in one way or another contains all the details to follow. I say “the faith of the new heaven and the new church” because heaven, where there are angels, and the church, in which there are people, act together like the inner and the outer levels in a human being. People in the church who love what is good because they believe what is true and who believe what is true because they love what is good are angels of heaven with regard to the inner levels of their minds. After death they come into heaven, and enjoy happiness there according to the relationship between their love and their faith. It is important to know that the new heaven that the Lord is establishing today has this faith as its face, doorway, and summary.
