The Lord's love is the sun of heaven, and it is natural for us to look above ourselves to the sun of this world in thinking about the Lord. It follows, then, that to be closer to the Lord we would climb into the highest places -- and indeed, people have been worshiping on mountains for ages. In fact, even steeples on modern churches are symbolic mountains. It makes sense, then, that a mountain in the Bible represents love to the Lord, the highest, purest love we human beings can experience. Mountains can also represent the desire for good that comes from the love of the Lord. Hills, meanwhile, represent a love of other people and a caring for them, and when "mountains" is used in the plural it generally represents both loves.

If someone has in his possession another person's goods without that person's knowing it, which makes it possible for him to keep them without fear of the law, loss of position, or loss of reputation, and yet he returns those goods to the other person because they are not his own, he has conscience. He does what is good for its own sake, and what is right for its own sake. Or if someone has the opportunity to attain an eminent position, and then, on seeing that another who seeks it is more useful to the country, yields the position to that other person for the sake of the country's good, he has conscience. And so on with all other examples.
