Mountain
In the Bible mountains were often considered holy places where God was worshiped. After the Lord freed the Israelites from slavery in Egypt, he brought them to Mount Sinai, where they first encountered God's full magnificence. It was also on this mountain that God gave Moses the Ten Commandments. On another high mountain, selected disciples saw Jesus Christ in his heavenly form: his face shining as brightly as the sun, his clothes tuning as bright as light itself.

Mountains are often places where God is worshiped, and he shows his glory.
