Mountains!

For ye shall go out with joy, and be led forth with peace: the mountains and the hills shall break forth before you into singing, and all the trees of the field shall clap their hands. --- Isaiah 55:12

And God said, Let the waters under the heaven be gathered together unto one place, and let the dry land appear: and it was so. And God called the dry land Earth; and the gathering together of the waters called he Seas: and God saw that it was good. --- Genesis 1:9,10

There's something about the scale and height and majesty of mountains that implants awe in the beholder. A visible strength and power is seen in them. Mountains have oftentimes been a source of protection and refuge for those needing rest or a place to hide. In Psalms 121 it says " I will lift up mine eyes unto the mountains, from whence cometh my help. My help cometh from the LORD, which made heaven and earth." God is so much more powerful than the largest mountain and its in Him that we find true protection and refuge.
