To John Booth Date: LONDON, January 29, 1791. MY DEAR BROTHER, You give me a very agreeable account of the progress of the work of God in your circuit. As to the poor self-conceited enthusiasts in Keighley, it seems best that you should never name them in public, but when occasion offers strike at the root of their errors by clearly proving the truth which they deny; and whenever you meet with any of them in private, then speak and spare not. Whenever you have opportunity of speaking to believers, urge them to go on to perfection. Spare no pains; and God, our own God, shall give you His blessing! I am Your affectionate friend and brother.
