The course of inexorable law cannot be turned aside by any sacrifice or offering, nor yet even by the free grace of God.
His development is chiefly noteworthy in regard to these two leading points - the relation of the evangelium or doctrine of free grace (I) to free will and moral ability, and (2) to the law and poenitentia or the good works connected with repentance.
In 1793 he published a treatise, The Calvinistic and Socinian systems examined and compared as to their moral tendency, in which he rebutted the accusation of antinomianism levelled by the Socinians against those who over-emphasized the doctrines of free grace.
He edited his father's incomplete History of the Work of Redemption, wrote in answer to Stephen West, A Dissertation Concerning Liberty and Necessity (1797), which defended his father's work on the Will by a rather strained interpretation, and in answer to Chauncy on universal salvation formulated what is known as the " Edwardean," New England or Governmental theory of the atonement in The Necessity of the Atonement and its Consistency with Free Grace in Forgiveness (1785).
The higher happiness is given to man by free grace of God; but it is given to those only whose heart is right, and as a reward of virtuous actions.
