136. Angels, like men, have understanding and will. The light of heaven makes the life of their understanding, because that light is Divine Truth and Divine Wisdom therefrom, and the heat of heaven makes the life of their will, because that heat is Divine Good and Divine Love therefrom. The veriest life of the angels is from heat, but not from light except in so far as it has heat in it. It is evident that life is from heat, for when heat is removed, the life perishes. The same is true of faith without love, or of truth without good. For the truth that is called the truth of faith is light, and the good that is called the good of love is heat.# This is more clearly shown by the heat and light of the world to which the heat and light of heaven correspond. From the heat of the world conjoined with light, all things upon the face of the earth are quickened and flourish. Heat and light are conjoined in the spring and summer seasons. But from light separated from heat nothing is quickened or flourishes but all things lie torpid and die. Heat and light are not conjoined in winter when heat is absent though light continues. From this correspondence heaven is called paradise since truth is there conjoined with good, or faith with love, as light is with heat in springtime on the earth. All this more clearly establishes the truth set forth in the appropriate section (n. 13-19) that "the Divine of the Lord in heaven is love to Him and charity towards the neighbour". # Truths without good are not in themselves truths, because they do not have life; for all the life of truth is from good (n. 9603). Truths apart from good are not accepted by the Lord (n. 4368). What truth apart from good, that is, what faith apart from love is, and what truth from good or faith from love is (n. 1949-1951, 1964, 5830, 5951). It amounts to the same thing whether you say truth or faith, or whether you say good or love, since truth is of faith and good is of love (n. 2839, 4352, 4353, 4997, 7178, 7623, 7624, 10367).
