The fabric of which this world is made is ever passing away; like a stream of water, drops are running away and others are following after, keeping the river still full, but always changing in its elements. But God is perpetually the same. He is not composed of any substance or material, but is spirit—pure, essential, and ethereal spirit—and therefore he is immutable. He remains everlastingly the same. There are no furrows on his eternal brow. No age hath palsied him; no years have marked him with the mementoes of their flight; he sees ages pass, but with him it is ever now. He is the great I AM—the Great Unchangeable.
==Charles Spurgeon , Sermon 1
