After noting that we should want to see the church increase by conversion growth (rather than sheep-stealing), Spurgeon warns that evangelism must be authentic:
But, still, all hurry to get members into the church is most mischievous, both to the church and to the supposed converts. I remember very well several young men, who were of good moral character, and religiously hopeful; but instead of searching their hearts, and aiming at their real conversion, the pastor never gave them any rest till he had persuaded them to make a profession. He thought that they would be under more bonds to holy things if they professed religion, and he felt quite safe in pressing them, for "they were so hopeful." He imagined that to discourage them by vigilant examination might drive them away, and so, to secure them, he made them hypocrites. These young men are, at the present time, much further off from the Church of God than they would have been if they had been affronted by being kept in their proper places, and warned that they were not converted to God. It is a serious injury to a person to receive him into the number of the faithful unless there is good reason to believe that he is really regenerate. I am sure it is so, for I speak after careful observation. Some of the most glaring sinners known to me were once members of a church; and were, as I believe, led to make a profession by undue pressure, well-meant but ill-judged. Do not, therefore, consider that soul-winning is or can be secured by the multiplication of baptisms, and the swelling of the size of your church. What mean these despatches from the battle-field? "Last night, fourteen souls were under conviction, fifteen were justified, and eight received full sanctification." I am weary of this public bragging, this counting of unhatched chickens, this exhibition of doubtful spoils. Lay aside such numberings of the people, such idle pretence of certifying in half a minute that which will need the testing of a lifetime. Hope for the best, but in your highest excitements be reasonable. Enquiry-rooms are all very well; but if they lead to idle boastings, they will grieve the Holy Spirit, and work abounding evil.
May the Lord be pleased to use our flock as in instrument in true evangelism.
Grace and peace, Pastor Jeff Riddle
