The faithful ambassador of Christ must therefore announce the command of God, "that all men every where should repent: and that unless they do repent, they shall all likewise perish.

He must divide his congregation into two classes, the friends and the enemies of God, those who are for the Saviour and those who are against him: and he must insist upon judging not by their profession, "Lord, Lord, but by the question, whether they _do the will of our Father in heaven_." Thus when the faithful servant of Christ represents all as unconverted, and exposed to the curse of the divine law, who do not give evidence of regeneration in their walk and conversation; careless sinners become alarmed and feel the necessity of fleeing from the wrath to come, by repenting and turning to God, by seeking pardon and a new heart, and consecrating all their powers of mind and body to the service of God.
But all this the believer in baptismal regeneration cannot consistenly [sic] do.

Because 1.

If we believe all our hearers _regenerated_, (for they are generally all baptised) even those whose life presents not the least evidence of piety, and many proofs to the contrary; we still must believe them in some sense the children of God, as they are born again! We cannot tell them that they are in the gall of bitterness and bonds of iniquity; because we profess to believe them regenerated-- therefore children of God in some sense.
2.

We cannot exhort the impenitent baptised, though apparently dead in trespasses and sins, to pray for a _new heart_ and a new spirit; for these, as regenerated persons, they have obtained.
