John Wesley, co-founder (with brother Charles) of Methodism:
You have nothing to do but to save souls. Therefore spend and be spent in this work. And go not only to those that need you, but to those that need you most. It is not your business to preach so many times, and to take care of this or that society; but to save as many souls as you can; to bring as many sinners as you possibly can to repentance. … Give me one hundred preachers who fear nothing but sin and desire nothing but God, and I care not whether they be clergymen or laymen, they alone will shake the gates of Hell and set up the kingdom of Heaven upon Earth.
