The Lord’s immutable nature is the foundation of our faith.

From Hebrews 1:10-12:  “In the beginning, Lord, You founded the earth, and the heavens are the work of Your hands; they will perish, but You remain; they will all wear out like clothing; like a cloak You will roll them up, and like clothing they will be changed.  But You are the same, and Your years will never end.”
