III. Those only can be warrantably employed in a ministry of the ordinances of Christ, and particularly in preaching the gospel, who are thereunto called by him, and admitted according to the rule laid down in the word. And none can be warrantably acknowledged and received as office-bearers, to whom that ministry is committed without some proper evidence of their being called and sent by Christ. "How shall they preach except they be sent?" Rom. x. 15. How, without this, can they do it warrantably or profitably? And, without some evidence of this, what ground have we to expect a blessing in waiting upon their ministry? It is not a mere providential sending that is here meant, as if there were no more necessity than abilities, and an opportunity of exercising them; for so the ministers of Satan may be sent, and a lying spirit was thus sent among the prophets of Ahab. But this sending means the call of Christ, intimated in such a way as to warrant the preacher, and with such evidence as may satisfy the conscience of the hearers, in receiving his ministry as the ordinance of Christ. A zeal for God, a strong desire of being useful to souls, and even a persuasion of having the call of Christ, cannot be sufficient warrant to the preacher; far less can the hearers, in receiving him, proceed upon grounds so uncertain. The apostles, and some other ministers in the beginning of the Christian dispensation, had an extraordinary call and immediate mission by Christ, and this was evidenced to all by the miraculous powers bestowed on them. These powers are now ceased, and it is vain to plead any such immediate call. The ordinary call of Christ to the work of the ministry is intimated by or through the church, judging thereof by the rules laid down in the word; and according to these rules, they that are found qualified and called, are to be admitted to the ministry by them who are already invested with it. The charge is given to the office-bearers of the church, to commit that ministry which they have received "to faithful men, who shall be able to teach others also," 2 Tim. ii. 2; Tit. i. 5. And for their direction in this matter, the qualifications necessary, both as to character and abilities, are laid down in the Word, particularly in 1 Tim. iii.; of these qualifications they are required to make an impartial and deliberate examination, so as to _lay hands suddenly on no man_, 1 Tim. iv. 22, but to admit to the office of the ministry those only, who, by this trial, they have reason to judge are called and sent by Christ.
