Goodness and truth resemble babies, in that they are
conceived, grow in the womb, are born, grow up, and increase in age until they reach full maturity. Conception,
gestation, and birth belong to their rise; growing up and
aging till they reach full maturity belong to their progress. The stage of progress, in which goodness and truth
unite, follows birth, and its start is what growing up symbolizes. This stage begins right after birth and continues
all the way to the end of life, and in people devoted to
goodness, it continues beyond bodily life to eternity. In
other words, angels are always developing.
