I hope I am not wrong in supposing that all of us are thoroughly sincere in our Master’s service. The command to the man who would be a true servant of the Lord Jesus Christ is, “Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy strength, and with all thy mind.” If a man is to be a soul-winner, there must be in him intensity of emotion as well as sincerity of heart. You may preach the most solemn warnings, and the most dreadful threatenings, in such an indifferent or careless way that no one will be in the least affected by them; and you may repeat the most affectionate exhortations in such a half-hearted manner that no one will be moved either to love or fear. I believe, brethren, that for soul-winning there is more in this matter of earnestness than in almost any thing else. I have seen and heard some who were very poor preachers, who yet brought many souls to the Saviour through the earnestness with which they delivered their message. It was not what the preachers said, so much as how they said it, that carried conviction to the hearts of their hearers. The simplest truth was so driven home by the intensity of the utterance and emotion of the man from whom it came that it told with surprising effect.
What earnestness our theme deserves! We have to tell of an earnest Saviour, an earnest heaven, and an earnest hell. How earnest we ought to be when we remember that in our work we have to deal with souls that are immortal, with sin that is eternal in its effects, with pardon that is infinite, and with terrors and joys that are to last for ever and ever! A man who is not in earnest when he has such a theme as this-can he possess a heart at all? Could one be discovered even with a microscope? If he were dissected, probably all that could be found would be a pebble, a heart of stone, or some other substance equally incapable of emotion. I trust that, when God gave us hearts of flesh for ourselves, He gave us hearts that could feel for other people also.
