I came across this quote awhile back when I was preaching through Exodus, and it profoundly moved me. It's from a Baptist pastor who ministered in London during the 19th century. I love the truth that "He loves, and He loves forever; and through the ages the fire burns on, unconsumed and undecayed." That is so powerful. It leads me to this humble prayer that God would make us the same in our love for Him and for each other. May our love burn unconsumed and undecaying.

And then, still further, notice that this flame is undying—steady, unflickering. What does that mean? Adopting the principle which I have already taken as our guide, that the symbol and the following revelation teach the same truth, there can be no question as to that answer. ‘I am the God of thy fathers, the God of Abraham, of Isaac, and of Jacob. “I AM THAT I AM”.’

That is to say, the fire that burns and does not burn out, which has no tendency to destruction in its very energy, and is not consumed by its own activity, is surely a symbol of the one Being whose being derives its law and its source from Himself, who only can say—‘I AM THAT I AM’—the law of His nature, the foundation of His being, the only conditions of His existence being, as it were, enclosed within the limits of His own nature. You and I have to say, ‘I am that which I have become,’ or ‘I am that which I was born,’ or ‘I am that which circumstances have made me.’ He says, ‘I am that I am.’ All other creatures are links; this is the staple from which they all hang. All other being is derived, and therefore limited and changeful; this Being is underived, absolute, self-dependent, and therefore unalterable for evermore. Because we live we die. In living the process is going on of which death is the end. But God lives forevermore, a flame that does not burn out; therefore His resources are inexhaustible, His power unwearied. He needs no rest for recuperation of wasted energy. His gifts diminish not the store which He has to bestow. He gives, and is none the poorer; He works, and is never weary; He operates unspent; He loves, and He loves forever; and through the ages the fire burns on, unconsumed and undecayed.
