David Brainerd

“It is the great business of every Christian to save souls. People complain that they do not know how to take hold of this matter. Why, the reason is plain enough; they have never studied it. They have never taken the proper pains to qualify themselves for the work. If you do not make it a matter of study, how you may successfully act in building up the kingdom of Christ, you are acting a very wicked and absurd part as a Christian.”
― Charles Finney
