To John Valton Date: LONDON, November 21, 1769. MY DEAR BROTHER, It is a great thing to be open to the call of God. It really seems as if He were now calling you. When I wrote last, you was not willing to go out; and probably He is now thrusting you out into His harvest. If so, take care you be not disobedient to the heavenly calling. Otherwise you may be permitted to fall lower than you imagine. I am Your affectionate brother.
