7082. There are two things in the natural world which make the life there, namely, heat and light; and there are two things in the spiritual world which make the life there, namely, love and faith. Heat in the natural world corresponds to love in the spiritual world, and light in the natural world corresponds to faith in the spiritual world. Hence it is that when spiritual heat or fire is mentioned, love is meant; and when spiritual light is mentioned, faith is meant. Moreover, love is actually the vital heat of man, for it is known that man grows warm from love; and faith is actually the light of man, for it can be known that man is illumined from faith.
