7625. The sun and its light may be used to form an idea of good which is synonymous with charity, and of truth which is synonymous with faith. When the light that emanates from the sun comes combined with heat, as happens in spring and summer, everything on earth grows and is alive. But when the light lacks heat, as in wintertime, everything on earth becomes inactive and dies off. In the Word also the Lord is compared to the sun, and truth combined with good which emanates from Him is compared to the light, in addition to which in the Word the truth of faith is called 'light' and the good of love 'fire'. Love is also 'the fire of life', and faith 'the light of life'.
