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.

4328. I have also been shown the situation in general with regard to the will part of the mind and the understanding part. The most ancient people who constituted the Lord's celestial Church, and who are described in 1114-1123, had a will which contained good and an understanding which contained truth derived from that good; and with them these two parts made one. The ancients however who formed the Lord's spiritual Church had a will that was completely destroyed, but an intact understanding within which, through regeneration, the Lord formed a new area of will, and through this a new area of understanding also, see 863, 875, 895, 927, 928, 1023, 1043, 1044, 1555, 2256.

[2] What the situation had been in the celestial Church so far as good was concerned was demonstrated by means of a blue-coloured column coming down from the sky, the left side of which was full of light, like the blazing light of the sun. This was a representation of the first state of those people, the blue colour representing their will, which was good, and the blazing light their understanding. After that the blue of the column turned to a dull red, which was a representation of their second state, a state in which their two kinds of life - that of the will and that of the understanding - still acted as one, though this was more dull so far as good from the will was concerned. For blue means good, and blazing light truth derived from good. After that the column became completely black, and surrounding the column there was a brightness which was variegated by means of something glittering and which presented colours. These changes meant the state of the spiritual Church. The black column meant that the will had been completely destroyed and that it was nothing but evil. The light variegated by something glittering meant the understanding in which a new will was provided by the Lord; for in heaven the understanding is represented by brightness.
