Mountain
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.
John 6:53-56
53
Jesus therefore said to them, "Most certainly I tell you, unless you eat the flesh of the Son of Man and drink his blood, you don't have life in yourselves.
54
He who eats my flesh and drinks my blood has eternal life, and I will raise him up at the last day.
55
For my flesh is food indeed, and my blood is drink indeed.
56
He who eats my flesh and drinks my blood lives in me, and I in him.
