Christ, The Foundation

"I now have found the firm foundation
Where evermore my anchor grounds!
It lay there ere the world's creation,
Where else, but in my Saviour's wounds?
Foundation which un-mov'd shall stay,
When earth and heaven pass away."

Truth is, most foundations aren't seen.  Only what we build upon them can be observed.  I was drawn to this wall by its being made of slate.  So much variation yet a wall nevertheless.  And obviously built on top of something sturdy.

"On this foundation I, unshrinking,
Will stand, while I on earth remain;
This shall engage my acting, thinking,
While I the breath of life retain.
Then I will sing eternally
Unfathomed Mercy, still of Thee!"

(Zion's Harp #221, v. 1, 6)
