Fifteen discourses upon doctrinal, connected subjects : with practical improvements, viz. On the primitive covenant of work, or law of nature. On the eternal obligation of the law of nature. On the universal condemnation of sinners by the law and covenant of works. On the impossibility of the sinner's justification, by the law, in the sight of God. On the imputation of righteousness without works. On the covenant of grace in general, or divine reconciliation. On the covenant of redemption, or mediation. On the first covenant, or law of Moses. On the second or better covenant of our Lord Jesus Christ. On faith and its connection with justification and holiness. Objections to the doctrine of justification in the vicarial way answered, and its consistence with the reward of virtue demonstrated. On Christian obedience as a new-covenant condition. On the perseverance of the saints, and final salvation of believers. On the final judgment, and justification and condemnation in that day. Recapitulation and reflections relative to the whole. / By John Mellen, A.M. Pastor of the Second Church in Lancaster.
