Two years into his apprenticeship Booth was converted. He then read extensively and trained himself in writing and in speech, becoming a Methodist local preacher. Booth was encouraged to be an evangelist primarily through his best friend, Will Sansom. Sansom and Booth both began in the 1840s to preach to the poor and the sinners of Nottingham, and Booth would probably have remained as Sansom's partner in his new Mission ministry, as Sansom titled it, if Sansom had not died of tuberculosis, in 1849.
