Mentioned in the sermon this morning, from George Müller,
There was a day when I died, utterly died — died to George Müller, his opinions, preferences, tastes, and will; died to the world, its approval or censure; died to the approval or blame even of my brethren and friends — and since then I have only to show myself approved to God.
Our pastor mentioned that he keeps this quotation in his wallet.
